Adjustable leveling feet fix the most common furniture problem — a leg that rocks on an uneven floor. They screw into a threaded insert, then turn by hand to set a level contact point on each leg. This guide covers every base style, thread size, and how to install them.
Adjusts by hand, no tools required · M4 to M12 plus 1/4″-20 and 5/16″-18 imperial · Stainless versions for outdoor and marine
Not sure where to start? This adjustable leveling feet guide narrows most applications down with three quick questions. (1) How much height clearance do you have under the furniture? Less than 10 mm needs low-profile or ultra-low; 10–25 mm fits standard; heavy loads benefit from wide base. (2) What thread size? Match the pre-tapped hole, threaded insert, or tube plug insert. M8 is the most common; M6 for lighter loads; M10–M12 for heavy. (3) Where will it live? Indoor furniture uses zinc-plated steel rods; outdoor, marine, or wet environments need stainless steel rod versions.
The rest of this adjustable leveling feet guide walks through each decision in detail. Hollow metal tube legs need a threaded-insert tube plug pressed in first; the leveling foot then threads into that insert.
The two most-used base styles in this adjustable leveling feet guide. The standard base covers the widest range of thread and stem lengths. The low-profile sits at just 9 mm tall for modern furniture and tight clearances. Both come with a pad included and notched-thread option for floor protection and vibration resistance.
The most versatile foot in this adjustable leveling feet guide. Tough PA base with a zinc-plated steel rod and plastic locking nut. Adjusts by hand and locks at the chosen height. Covers the widest range of threads (M6 to M12 plus imperial) and stem lengths (10–110 mm). Variants include an integrated PA6 pad for floor protection and a notched-thread version that resists loosening from vibration.
M6 × 10–63 mm, M8 × 10–43 mm, M10 × 28–63 mm. The everyday standard base.
M8 × 28–110 mm, M10 × 28–60 mm, M12 × 25–45 mm. For heavier furniture and longer reach.
M6, 1/4″-20, 5/16″-18. PA6 floor-protection pad on the base face. Hardwood and tile.
M8 × 35 mm or M10 × 50 mm. Notched rod resists loosening from vibration.
M10 × 50 mm. Heavy equipment, commercial fixtures, vibration-prone applications.
Colors: Black, Grey, White. In this adjustable leveling feet guide, the standard base is the default starting point when no other constraint forces a different style.
9 mm total height — the most popular style for modern furniture sitting close to the floor. Same construction as the standard base in a slimmer form factor. Pad and notched-thread variants available. For furniture designed to sit nearly flush, the ultra-low profile foot is just 6 mm tall — the lowest profile in the catalog.
M4 × 10 mm or M6 × 8–19 mm. Small lightweight furniture, designer pieces.
M8 × 10–48 mm, M10 × 18–50 mm. Dining chairs, desks, tables on hardwood.
M8 × 14–48 mm. PA6 pad built into the base face. Low-profile + floor protection.
M4 × 10 mm. Compact appliances and equipment subject to vibration.
M8 × 30 mm. Low-profile + vibration-resistant for larger equipment.
M8 × 21 mm or M10 × 20 mm. Flush-to-floor modern furniture.
Colors: Black, Grey, White. The low-profile section of this adjustable leveling feet guide covers four variants total: standard low-profile, with-pad, notched-thread, and ultra-low.
When the standard or low-profile base is not the right fit. The specialty chapter of this adjustable leveling feet guide covers wide bases for heavy loads, slim and mini for design-led applications, smooth-base for clean visible profiles, and self-leveling tilt or ball-joint feet for uneven floors.
In this adjustable leveling feet guide, the Ø 50 mm base distributes load across a larger footprint for heavy furniture, workbenches, and commercial equipment where standard bases would concentrate too much pressure on a small area. Available in standard polymer and anti-slip TPE versions. M8 thread; 23 mm and 28 mm stem lengths.
PA base. Heavy tables, workbenches, server racks. The default wide base.
PA base, longer stem. Heavier equipment, commercial shelving with more reach.
TPE rubber base. Fixed-position heavy equipment on smooth hard floors.
In this adjustable leveling feet guide, the anti-slip TPE version grips the floor instead of gliding — use it for heavy equipment that must hold position. The standard PA version is the default choice for workshop, lab, and commercial furniture.
Three purpose-built bases in this adjustable leveling feet guide for design-led applications. The slim base (Ø 40 mm) gives a clean, intentional profile under contemporary furniture. The mini (Ø 13 mm) is the smallest foot in the catalog for delicate pieces where a standard base would look oversized. The smooth base (Ø 30 mm) hides all hardware on the base face for a finished look; a hex-key version adds precise sub-millimeter adjustment with an Allen key.
M8 × 20 mm. Clean-profile base for contemporary furniture. Intentional, not industrial.
M6, stem 15 or 20 mm. Smallest base in the catalog for small, lightweight furniture.
M8 × 28/33 mm or M10 × 18/33 mm. Rounded profile, no exposed hardware on the base face.
M8 × 14/33 mm or M10 × 33 mm. Hex-key socket on top face for precise Allen-key adjustment.
For floors with significant slope, this adjustable leveling feet guide covers two self-compensating options skip the per-leg adjustment step. The tilt foot uses a pivoting base that auto-levels up to 9° of floor slope on one axis — most useful for dining tables and desks. The ball-joint foot has a full 360° pivot for furniture on sloped floors, ramps, or angled surfaces where the slope direction varies. Both maintain full base-to-floor contact without manual adjustment.
M8 × 30 mm, M10 × 30–50 mm. Auto-compensates floor slope. Dining tables, desks.
M10 × 30–50 mm. Wider base for heavier furniture on uneven floors.
M4 × 10 mm. Compact 360° pivot for small furniture on sloped surfaces.
M8 × 30 mm. Standard 360° pivot for larger furniture on ramps or angled floors.
Standard and low-profile bases with a stainless steel rod instead of zinc-plated steel. For outdoor furniture, marine environments, food-service equipment, and any application where corrosion resistance is required. The stainless rod resists salt spray, humidity, and cleaning chemicals that corrode standard zinc-plated rods over time. This stainless chapter of the adjustable leveling feet guide covers three configurations for the most common needs.
Polymer base with a stainless steel rod instead of zinc-plated steel. The most common stainless configuration. Resists salt spray, humidity, and cleaning chemicals that corrode standard rods over time. Ø 30 mm and Ø 45 mm bases. Threads M6 to M10. Black and Grey.
M6 × 18 mm, M8 × 24–28 mm, M10 × 28 mm. Outdoor furniture, wet rooms, food service.
M10 × 28–40 mm. Commercial outdoor and marine equipment. Heavier-duty stainless option.
In this adjustable leveling feet guide, use the stainless version for any indoor application with regular floor washing (commercial kitchens, healthcare floors) and all outdoor or marine installations.
Low-profile polymer base with stainless steel rod. 9 mm height plus corrosion-resistant hardware. For outdoor and marine furniture where a low-profile foot is required and the rod will see moisture or chemicals.
M6–M10 with 9 mm base height. Outdoor low-profile furniture; salt-spray resistance.
Anti-slip TPE base with a stainless steel rod and stainless hex nut. Stainless throughout. The TPE base grips smooth, hard floors instead of gliding. For marine equipment, outdoor fixtures, and food-service applications where both grip and corrosion resistance are required. Distinctive blue base color makes it easy to identify in service.
M8 × 35 mm. Blue TPE base + stainless rod + stainless nut. Marine, food service, hygiene-critical.
This is the only fully-stainless foot in the adjustable leveling feet guide — base hardware, rod, and locking nut are all corrosion-resistant.
The measurement chapter of this adjustable leveling feet guide is the most important to read carefully. Get the thread size right and everything else falls into place. Get it wrong and the foot will not thread in. Three measurements pin down the right foot: thread size, base diameter, and stem length.
| What to Measure | How to Measure | What It Determines |
|---|---|---|
| Thread size | Read the marking on the pre-tapped hole, threaded insert, or tube plug insert. Common: M6, M8, M10, M12; imperial 1/4″-20, 5/16″-18. | Which foot thread to order. Must match exactly. |
| Base diameter | Measure clearance under the leg with calipers or a ruler. Account for any decorative trim or skirt. | Standard (Ø 30/45 mm), low-profile (Ø 20/30 mm), wide base (Ø 50 mm), or specialty. |
| Stem length | How much height adjustment range is needed? Measure floor unevenness across the whole footprint of the furniture. | Short stems (8–20 mm) for level floors; long stems (40–110 mm) for big slope or seasonal adjustment. |
| Environment | Indoor dry, indoor wet, outdoor, or marine? Will the foot see cleaning chemicals or salt spray? | Zinc-plated steel rod (default) or stainless steel rod (outdoor, marine, food service). |
Tip: when in doubt, measure the existing foot
If you are replacing leveling feet on existing furniture, take one of the old feet out and bring it to the measurement. The thread on the rod and the diameter of the base tell you exactly what to order. This is the single fastest way to avoid a wrong-size mistake on commercial fit-outs.
Hollow metal tube legs need a separate measurement for the tube wall thickness before selecting a threaded-insert tube plug. See the tube plug pairing chapter below for the full two-part install.
The plug-pairing chapter of this adjustable leveling feet guide covers a common question: hollow metal tube legs have no threads to accept a leveling foot directly. The fix is a two-part install. Press a threaded-insert tube plug into the open tube end, then thread the leveling foot into the metal nut inside the plug. No drilling, no welding, no adhesive. The plug grips the tube wall mechanically; the foot threads in by hand. This pairing makes any hollow-tube furniture leg leveling-compatible.
Select a threaded-insert tube plug matching three things: the tube profile (round, square, or rectangular), the tube wall thickness, and the thread size you need (M6, M8, M10, or M12). The plug shape and wall thickness determine grip; the thread determines what leveling foot fits inside.
Set the plug into the open tube end and press down. The ribbed outer wall compresses slightly and springs back to grip the tube wall mechanically. No adhesive needed. Most sizes go in by hand; tight fits may benefit from a wood block and rubber mallet. The plug head should sit flush with the tube face when fully seated.
Match the leveling foot thread size to the insert (M6 foot for M6 plug, and so on). Thread by hand from below; clockwise raises the furniture, counter-clockwise lowers. Adjust each leg until level, then tighten the locking nut. The result is a fully adjustable, removable leveling solution on any hollow metal tube leg.
Pre-tapped hole and threaded insert sizes vary by furniture type and manufacturer. The lookup chapter of this adjustable leveling feet guide narrows the most likely base style, thread size, and stem length for common furniture categories. Use it as a starting point, then confirm with the actual measurement.
| Furniture Type | Most Common Base | Thread | Notes |
|---|---|---|---|
| Dining chairs | Low-profile, Ø 30 mm | M8 | Hollow tube legs need a threaded-insert tube plug first. |
| Dining tables | Standard, Ø 30–45 mm | M8, M10 | Longer stems (40–60 mm) for floors with seasonal movement. |
| Office desks | Low-profile, Ø 30 mm | M8 | Hex-key version is useful for shared workstations needing height fine-tuning. |
| Office chairs (5-star) | Mini or low-profile, Ø 20 mm | M6 | Often a press-fit plug, not threaded — confirm before ordering. |
| Conference tables | Standard, Ø 45 mm | M10, M12 | Long boards see seasonal movement; tilt foot can help if needed. |
| Workbenches / shop tables | Wide base, Ø 50 mm | M8 | Heavy static loads need wide-base distribution; anti-slip for shop floors. |
| Server racks / IT cabinets | Wide base, Ø 50 mm | M8 | Anti-slip TPE base keeps the rack from creeping under operation. |
| Outdoor / marine furniture | Stainless rod, standard or low-profile | M8, M10 | Use stainless rod version for any salt-spray, humid, or wet environment. |
| Commercial kitchens | Stainless rod, standard | M8, M10 | Anti-slip stainless for food-service equipment that must hold position. |
| Cabinets / kitchen units | Low-profile, Ø 20–30 mm | M6, M8 | Long stems (30–50 mm) for floor leveling across the full base width. |
| Bar stools | Low-profile, Ø 30 mm | M8 | Often tube legs — plug + foot pairing applies. |
| Sled-base chairs | Low-profile or specialty | M6, M8 | If the sled has a rectangular tube end, use a rectangular tube plug + foot. |
If your furniture is not listed, the safest path is to remove one of the existing feet (or measure the threaded insert directly) and order a matching size. The thread size and base diameter on the old part tell you exactly what to order new.
The materials chapter of this adjustable leveling feet guide covers the four materials used across the range. PA polymer is the main base material. POM is used for the smallest precision bases. TPE provides the anti-slip floor-contact layer. The threaded rod is either zinc-plated steel (default) or stainless steel (outdoor and marine).
PRECISION SMALL BASES
Higher dimensional stability and tighter tolerances than PA at small diameters. POM is used on the mini base (Ø 13 mm) where the small size demands precision threading and a rigid base structure. The reason mini bases stay round and threads stay clean at such a small diameter.
Used in: mini base feet (Ø 13 mm). Temperature range: −40 to +85°C. Properties: high dimensional stability, low creep, good machinability.
MAIN BASE MATERIAL
Polyamide is the main base material across the catalog. Tough, load-rated, resistant to commercial cleaning chemicals. Low friction coefficient. PA is what gives leveling feet their structural strength under sustained load.
Used in: standard, low-profile, wide-base, slim, smooth, tilt, and ball-joint bases. Temperature range: −40 to +85°C. Load: rated per individual foot.
ANTI-SLIP GRIP LAYER
Combines rubber characteristics with plastic processability. Excellent abrasion resistance. Used as the floor-contact layer on anti-slip versions — grips smooth hard floors instead of gliding. The difference between heavy equipment that stays put and equipment that creeps under operation.
Used in: wide-base anti-slip foot and anti-slip stainless foot. Temperature range: −51 to +124°C. Properties: high friction coefficient on smooth hard floors.
THREADED ROD
Fe HDG (hot-dip galvanized iron): the standard threaded rod on indoor leveling feet. Stainless steel (304): corrosion-resistant rod for outdoor, marine, food-service, and wet-room applications where the rod will see salt spray, humidity, or cleaning chemicals.
Used in: threaded rod across all adjustable leveling feet. Diameters: M4, M6, M8, M10, M12, plus imperial 1/4″-20 and 5/16″-18. Same load ratings, different material costs.
The installation chapter of this adjustable leveling feet guide covers the standard four-step install. Adjustable leveling feet thread in by hand, adjust by hand, and lock with a finger-tight nut. The installation chapter of this adjustable leveling feet guide is straightforward: no tools needed for the standard, low-profile, wide-base, specialty, or smooth-base feet. Hex-key versions add an Allen key for sub-millimeter precision; tilt and ball-joint versions auto-compensate for slope.
Thread the leveling foot into the pre-tapped hole or threaded insert from below. Turn clockwise to raise the furniture, counter-clockwise to lower. For hollow tube legs, press a threaded-insert tube plug into the tube first, then thread the foot into the plug insert. Stop when the base of the foot is close to the floor.
Place the furniture upright on the floor. Each foot should make contact. Spin individual feet up or down by hand until the furniture sits roughly level. This is the rough pass — don’t worry about getting it perfect yet.
Place a spirit level on the furniture top. Adjust each foot independently until the bubble sits centered along both axes. Hex-key versions let you do this with an Allen key for precise sub-millimeter changes. Tilt and ball-joint feet skip this step — they auto-compensate.
Once level, slide the locking nut down the foot rod and tighten it against the underside of the furniture base by hand. This jams the foot against the furniture and stops it from rotating during use. Notched-thread versions hold position without a locking nut — the notches resist rotation from vibration.
Hollow metal tube legs: press a threaded-insert tube plug into the open tube end first. The plug ribs grip the tube wall mechanically. Then thread the leveling foot into the metal nut inside the plug. Choose the plug shape (round/square/rectangular), thread size, and tube wall thickness to match.
Hex-key adjustment: on smooth-base hex-key feet, the height adjustment is done from above with an Allen key inserted into the socket on the top face. This makes fine adjustment possible without crawling under the furniture.
Tilt and ball-joint feet: no per-leg leveling needed. Install all four feet, set them to roughly equal heights, and let the pivoting base compensate for floor slope automatically.
Removable and reusable
Adjustable leveling feet are threaded fasteners — they screw in and out without damaging the furniture. To remove, loosen the locking nut and unscrew the foot by hand. The same foot can be reused in a new piece of furniture as long as the thread size matches. For replacements, match the thread, base diameter, and stem length of the old part.
Two ways to fix a rocking leg. The comparison chapter of this adjustable leveling feet guide weighs shimming (cardboard, wedges, plastic shims) against threaded adjustable leveling feet. Both work as a quick fix; only one is the right longer-term solution for furniture that stays in place.
ADJUSTABLE LEVELING FEET
SHIMMING / WEDGES
These are the questions we get most often about adjustable leveling feet. If you do not see your question, our specialists will help you match the right base style, thread size, and stem length to your furniture or equipment. The FAQ chapter of this adjustable leveling feet guide covers the most common edge cases.
The standard base is taller (about 14–18 mm) and comes in Ø 30 mm and Ø 45 mm diameters with the widest thread and stem-length selection in the range (M6 to M12, stems 10–110 mm). The low-profile base is just 9 mm tall and comes in Ø 20 mm and Ø 30 mm diameters with M4 to M10 threads. Pick standard for traditional furniture where the foot is hidden under a skirt; pick low-profile for modern furniture sitting close to the floor.
The thread on the leveling foot must match the pre-tapped hole or threaded insert exactly. Common metric sizes are M6, M8, M10, and M12; common imperial sizes are 1/4″-20 and 5/16″-18. If you are replacing existing feet, the fastest way to know is to remove one and read the thread marking on the rod. For new installations, the threaded insert or tube plug determines the thread size.
The pad version has a PA6 floor-protection pad bonded to the base face. Use it when the furniture sits directly on hardwood, tile, or vinyl and you want the leveling foot to also protect the floor. For furniture on carpet, the pad is unnecessary; the carpet already protects the floor. For wide-base feet on workbenches and equipment, the pad is not typically needed because the base area distributes load.
Load capacity varies by base style, thread size, and rod material. Wide-base Ø 50 mm feet are rated for the heaviest static loads (commercial workbenches, server racks, industrial equipment). Standard Ø 30–45 mm bases handle typical furniture and commercial seating. Mini and ultra-low feet are for light furniture only. Check the individual product page for exact static load ratings before specifying for heavy commercial use.
Specify the stainless rod version for outdoor furniture, marine environments, commercial kitchens, healthcare floors with daily chemical cleaning, and any wet-room application. The stainless rod resists salt spray, humidity, and cleaning chemicals that corrode standard zinc-plated rods over time. For normal indoor environments (residential, office, retail) the standard zinc-plated rod is the right choice at lower cost.
The hex-key version has an Allen-key socket on the top face of the base. This lets you fine-tune height with an Allen key from above instead of spinning the whole foot from below. Use it for shared workstations where users adjust their own desk height, precision-leveled equipment that needs sub-millimeter accuracy, and any installation where reaching under the furniture is awkward.
Yes, but choose the base style carefully. A wide Ø 50 mm base distributes weight and resists sinking into the carpet pile. Standard Ø 30 mm bases work on short-pile carpet. Avoid small bases (mini, Ø 20 mm low-profile) on plush carpet — they push down into the pile and the furniture rocks. Anti-slip TPE versions are not needed on carpet; the carpet itself prevents sliding.
The tilt foot has a pivoting base that automatically compensates for floor slope up to 9° on one axis. Instead of adjusting each leg manually to level the furniture, the tilt foot maintains full base-to-floor contact as the floor tilts. Useful for dining tables and desks on uneven tile or concrete floors. The ball-joint version goes further: full 360° pivot for furniture on ramps, sloped floors, or angled surfaces.
Most leveling feet have a PA (polyamide) base — tough, load-rated, resistant to commercial cleaning chemicals. Mini bases use POM (polyoxymethylene) for the higher precision tolerance needed at Ø 13 mm. Anti-slip versions use TPE (thermoplastic elastomer) for the grip layer that contacts the floor. The threaded rod is zinc-plated steel (Fe HDG) on standard versions and 304 stainless steel on outdoor/marine versions.
Hollow tube legs have no threads to accept a foot directly. The workaround is a two-part install: press a threaded-insert tube plug into the open tube end, then thread the leveling foot into the metal nut inside the plug. The plug grips the tube wall mechanically without adhesive or tools. Match the plug shape to the tube (round, square, or rectangular) and the plug insert thread size (M6, M8, M10, or M12) to the leveling foot you want to use.
Yes. Adjustable leveling feet thread in and out of standard tapped holes or threaded inserts. Loosen the locking nut, then unscrew the foot by hand. The same foot can be installed in a new piece of furniture as long as the thread size matches. Notched-thread versions are also reusable — the notches resist rotation under vibration but do not prevent intentional removal.
The locking nut is a plastic nut threaded onto the foot above the base. Once you have dialed in the right height, tighten the nut up against the furniture base. This jams the foot against the furniture and stops it from rotating during use. Without the locking nut, vibration or someone leaning on the table can slowly turn the foot and change its height. Notched-thread versions work without a locking nut for compact equipment, but on furniture that gets bumped regularly, the locking nut is the cleaner solution.
