100mm Bolt down top adjusting levelling foot black base

What are 100mm Bolt-Down Top Adjusting Levelling Feet (Black Base)?

Top adjusting bolt-down levelling feet from WDS Components are premium adjustable mounts engineered to provide exceptional structural stability, precise height alignment, and permanent floor anchoring. Featuring an expanded 100mm diameter black base, this range is available in standard heavy-duty metric M12 and M16 thread sizes. They are manufactured with a high-strength polypropylene copolymer base and a marine-grade 316 stainless steel stem, incorporating an extended base section with a single integrated fixing hole to bolt the foot directly to the floor.

The standout feature of this parent range is the integrated hexagon socket broached directly into the top of the fully threaded stud. This allows installers and maintenance engineers to make effortless height adjustments from above using a standard drive tool—completely eliminating the struggle of reaching beneath heavy, low-clearance machinery frames where access is heavily restricted. For added installation versatility, a conventional hex profile at the base of the stem allows for traditional wrench adjustment from below. Each foot is finished with an articulated, press-fitted ball joint that tilts to automatically negotiate sloped or angled flooring, resting on a high-grip 75 Shore A nitrile rubber pad that dampens operational noise and absorbs structural vibrations.

Key Features & Benefits

• Secure Bolt-Down Fixing Hole: The extended base profile features a single dedicated mounting hole, enabling mechanical floor anchoring to eliminate equipment drift and maximize workplace safety.
• M12 & M16 Metric Thread Options: Available in popular M12 and M16 coarse-pitch metric threads, providing strong, reliable engagement for medium-to-heavy industrial frames and enclosures.
• Stable 100mm Diameter Base: The 100mm footprint delivers an expanded, wide foundation that significantly increases load distribution while maintaining a clean, professional profile on large structural frames.
• Top-Down Drive Adjustment: Top hexagon socket lets operators level equipment from above, maximizing maintenance efficiency when space underneath is restricted.
• Dual-End Adjustment Flexibility: Features a bottom hexagonal profile alongside the top socket, offering two distinct ways to adjust height depending on your layout.
• Tilting Base: The internal press-fitted ball joint allows the foot to pivot, securely anchoring machinery on uneven, angled, or sloped flooring.
• 316 Stainless Steel Stem: Provides elite corrosion resistance against moisture and industrial fluids, preventing thread binding and ensuring lifelong adjustability.
• High-Grip Nitrile Pad: Built-in 75 Shore A rubber base pad prevents slipping, absorbs harsh machinery vibrations, and eliminates floor scratching.

Typical Industrial Applications

These floor-anchoring, dual-adjustable mounts are purpose-built to level and secure high-vibration systems, automated lines, and safety enclosures across demanding manufacturing facilities:

• Manufacturing & Assembly Line Workstations
• Material Handling & Conveyor Networks
• Automation & Packaging Enclosures
