Heavy commercial furniture often sits in positions where hand access to the leveling feet is restricted: conference tables against walls, industrial workbenches in tight layouts, kitchen prep tables loaded with equipment. On furniture this heavy, tipping the piece to access the feet is impractical. Notched thread standard base adjustable leveling feet solve this with a screwdriver slot in the threaded rod end. Insert a flathead screwdriver from above through the furniture tube leg, engage the slot, and turn the rod to adjust the height. M10 at 120 kg per foot handles the heaviest commercial applications.
PA (polyamide) standard base (Type A) with zinc-plated steel M10 threaded rod featuring a screwdriver notch. Notched thread standard base adjustable leveling feet are from-above standard base leveling feet for heavy furniture where hand access below is limited. Ø 30 mm (H = 18 mm) and Ø 45 mm (H = 19 mm). M10 x 50 mm. Static load: 120 kg per foot. 2 variations. Black. Sold individually.
Both variations share the M10 x 50 mm threaded rod with screwdriver notch and the 120 kg per foot load capacity. Choose the base diameter based on your furniture leg size and desired floor contact area.
Standard base (18 mm). 120 kg per foot (480 kg on four legs). Weight: 38.2 g. 707 mm² floor contact. For furniture with legs under 40 mm where the foot should stay proportional. Black. Compatible with M10 round, square, and rectangular threaded inserts.
Standard base (19 mm). 120 kg per foot (480 kg on four legs). Weight: 46.2 g. 1,590 mm² floor contact. For heavy furniture where broader contact improves stability and load distribution. Black.
For notched thread on low-profile base (M8, 80 kg): notched thread low-profile. For hex-key from-above on smooth base: smooth-base hex-key. For standard base without notch: standard base adjustable leveling feet. For custom configurations, contact Business Solutions.
The notch is a straight slot machined into the top end of the M10 threaded rod. When installed, the slot faces upward, accessible through the hollow tube leg from above. The adjustment process is the same as the notched thread low-profile version, but at a heavier load capacity.
If the tube top has a tube plug or square plug, remove it. Insert a flathead screwdriver down through the tube to reach the rod end. Seat the blade in the straight slot.
Clockwise extends the foot (raises). Counterclockwise retracts (lowers). The M10 thread pitch provides precise height adjustment per turn. The 50 mm rod gives significant total adjustment range for uneven floors.
Check the furniture level after each foot adjustment. Move to the next leg. Replace any tube plugs removed for access. The standard base sits at 18-19 mm under the leg throughout.
Both notched thread standard base adjustable leveling feet carry the same M10 load (120 kg per foot) with the same 50 mm rod. The difference is the floor contact area and the visual proportion relative to the furniture leg.
707 mm² of floor contact. 18 mm base height. For furniture with legs in the 25 to 35 mm range where the Ø 30 base sits proportionally under the leg. The compact base stays closer to the leg diameter, reducing visible overhang. On conference tables and office desks with standard round tube legs, the Ø 30 base matches the typical leg proportion.
1,590 mm² of floor contact, 2.25 times the Ø 30 area. 19 mm base height. For heavier furniture where broader contact provides better load distribution and stability. Industrial workbenches, heavy conference tables, and commercial kitchen prep tables benefit from the wider base. Notched thread leveling feet M10 on the Ø 45 base provide the highest stability with from-above adjustment.
Notched thread standard base adjustable leveling feet serve heavy furniture that needs from-above adjustment access on a standard-height base. The M10 thread at 120 kg per foot and 50 mm rod handle the weight and floor conditions found in commercial and industrial environments.
Same screw-in process as any standard base leveling foot. The notch does not change installation. It only adds from-above adjustment after the foot is installed.
For furniture manufacturers, notched thread standard base adjustable leveling feet add from-above adjustment to the standard base without changing any other specification. Two part numbers: Ø 30/M10 x 50 and Ø 45/M10 x 50. Choose the base diameter based on the furniture leg size and desired floor contact area.
On commercial projects where heavy furniture will be serviced by maintenance teams, specifying notched thread standard base adjustable leveling feet ensures every heavy table and workbench can be leveled with one common flathead screwdriver. No hex keys, no specialty wrenches. The same screwdriver that levels the notched thread low-profile desks also levels the notched thread standard base conference tables and workbenches. One tool for the entire furniture fleet. For production quantities, visit Business Solutions.
Notched thread standard base adjustable leveling feet use the same PA base as non-notched standard base feet. Floor compatibility is identical: hardwood, engineered wood, luxury vinyl, tile, polished concrete, laminate, sealed stone, and any other standard hard floor surface. The PA base provides non-scratching, non-marking contact.
In industrial environments where the floor is rough concrete with aggregate exposure, the standard base at 18-19 mm provides clearance between the floor surface and the tube end. This clearance keeps debris from packing between the tube and the floor. The 50 mm rod handles the unevenness typical of industrial concrete floors where settling, repairs, and expansion joints create height variations across the floor surface.
All leveling feet share the same M-thread interface. On heavy furniture where two legs sit against a wall and two face the room, use notched thread standard base adjustable leveling feet on the wall-side legs (from-above access needed) and standard non-notched feet on the room-side legs (hand access easy). Both use M10, both carry 120 kg, and the base dimensions can match if you select the same diameter.
This selective approach uses notched thread feet only where from-above access provides practical value. On commercial orders, this can reduce the notched thread quantity while maintaining from-above access where it matters most. For furniture that moves between positions where different legs face the wall at different times, notched thread on all legs provides consistent access regardless of orientation.
Height adjustment on heavy furniture with from-above screwdriver access on a standard base. The National Wood Flooring Association (NWFA) recommends protective contact surfaces on all furniture legs, and the standard PA base provides the same non-scratching floor contact at Ø 30 or Ø 45 as non-notched versions.
The primary advantage. A 200 kg conference table loaded with monitors and documents cannot be tipped for hand access to the feet. A flathead screwdriver through the tube from above reaches the notch and adjusts the foot while the table stays in place with everything on it. Flathead adjustable leveling feet standard base that solve the access problem on the heaviest commercial furniture.
The low-profile notched version handles 80 kg per foot on M8. The smooth-base hex-key also handles 80 kg on M8. Notched thread standard base adjustable leveling feet are the only from-above adjustable feet in the range at 120 kg per foot. Unlike leaving heavy furniture improperly leveled due to access difficulty, the notch makes re-leveling practical on furniture that would otherwise go un-adjusted.
Commercial and industrial floors are often more uneven than residential floors. Settled concrete, expansion joints, drainage slopes, and floor patch repairs create height variations that shorter rods cannot compensate for. The 50 mm rod on notched thread standard base adjustable leveling feet provides the adjustment range these floors demand. Combined with from-above screwdriver access, re-leveling after floor repairs or furniture relocation is quick.
Same advantage as the low-profile version: a flathead screwdriver is the most universally available hand tool. In commercial facilities where maintenance teams service large furniture fleets, one screwdriver handles every notched thread foot in the building. Screwdriver standard base leveling feet that require no specialty tools for from-above adjustment on the heaviest furniture in the range.
Same PA body and zinc-plated steel rod as non-notched standard base leveling feet. The only addition is the screwdriver slot machined into the M10 rod end.
Ø 30 mm at 18 mm height (707 mm²) or Ø 45 mm at 19 mm height (1,590 mm²). Same PA material properties as all standard base feet: UV resistant, chemical resistant, moisture resistant, non-scratching floor contact. The standard base height provides clearance between the floor and the tube end for debris clearance and visual inspection access.
M10 x 50 mm on both variations. Zinc plating for corrosion resistance. The screwdriver slot is machined perpendicular to the rod axis at the rod end. The slot does not affect thread engagement or load capacity. For stainless steel rods in corrosive environments, see stainless steel rod leveling feet.
Notched thread low-profile has a 9 mm base with M8 at 80 kg. Standard base has 18-19 mm with M10 at 120 kg. Same notch feature, different base height and load capacity. Choose based on furniture weight and visibility preference.
Standard base without notch adjusts by hand only but offers M6 to M12 with rods up to 110 mm. Notched thread is M10 x 50 only, but adds screwdriver access from above. Choose standard for more size flexibility. Choose notched for from-above convenience at 120 kg.
Smooth-base hex-key uses Allen wrench on smooth base, M8 at 80 kg. Different tool, different base, lower load capacity. Choose hex-key for smooth sliding at lighter loads. Choose notched standard base for heavier loads with screwdriver access.
Heavy conference tables in boardrooms, industrial workbenches in manufacturing facilities, commercial kitchen prep tables, and heavy retail display fixtures. These are the heaviest furniture pieces in any building, and they are often the hardest to access for leveling because of their weight, their position against walls, and the items loaded on top. Notched thread standard base adjustable leveling feet provide M10 at 120 kg with screwdriver access from above. One person with one screwdriver levels a 400 kg table without help, without moving the table, and without clearing the tabletop. In facility maintenance, this transforms leveling from a scheduled two-person task into a quick single-person walkthrough. Available for bulk orders. For commercial pricing, visit Business Solutions.
Heavy solid-wood dining tables, stone-top kitchen tables, and large home office furniture where the furniture is too heavy for one person to tip. The flathead screwdriver is already in the toolkit. No special tools needed. For homeowners who value their hardwood or luxury vinyl floors, the standard PA base on notched thread standard base adjustable leveling feet provides the same non-scratching contact as any standard base foot, with the added convenience of from-above adjustment when the table sits against the dining room wall or in a breakfast nook corner.
For furniture with round, square, or rectangular threaded inserts with M10 threads, notched thread standard base adjustable leveling feet provide the simplest from-above adjustment method at the highest load capacity available in the from-above adjustable range. The 50 mm rod handles the floor unevenness found in older homes with settled foundations.
Check periodically that the foot is tight and the furniture remains level. The standard base at 18-19 mm is more visible during inspections than low-profile feet, making visual checks easier. Before using the screwdriver, confirm the notch slot is clean. On furniture in dusty environments (workshops, kitchens), clean the rod end area before inserting the screwdriver.
Notched thread standard base adjustable leveling feet are sold individually for single-foot replacement. Use a flathead screwdriver that fits the slot width snugly. If the slot becomes rounded from an undersized blade or excessive force, replace the foot. The PA base and zinc-plated rod do not degrade under normal indoor conditions.
Notched Thread Low-Profile: 9 mm base, M8, 80 kg.
Standard Base: M6 to M12, rods to 110 mm, hand adjustment.

Notched thread low-profile has a 9 mm base with M8 at 80 kg. This product has a standard 18-19 mm base with M10 at 120 kg. Choose low-profile for minimal foot visibility at lighter loads. Choose standard base for heavier furniture where the taller base clearance and M10 load capacity are needed.
M10 at 120 kg per foot serves the heavy furniture category where standard base notched thread is most commonly specified. The 50 mm rod provides significant adjustment range for uneven commercial and industrial floors. The two base diameters (Ø 30 and Ø 45) allow matching the foot proportion to the furniture leg diameter.
Choose Ø 30 (707 mm² contact) for furniture with legs under 40 mm where the foot should stay proportional. Choose Ø 45 (1,590 mm² contact) for heavier furniture where broader floor contact improves stability and load distribution. Both carry 120 kg per foot with the same M10 x 50 mm rod.
A manual flathead screwdriver is recommended. Power drivers can deliver excessive torque that strips the slot. If using a powered driver, set it to the lowest torque setting and stop as soon as resistance increases. The notch is designed for hand-tool torque, not power-tool torque.
Yes. M10 thread, identical to all M10 leveling feet. Compatible with M10 round, square, and rectangular threaded inserts. Swap between notched and non-notched M10 feet without changing inserts.
