Vlier SC328 Swivel Pad Leveling Screw 1/4-20 1 Inch

Product Description

The VLIER SC328 is a swivel pad leveling screw designed for precision positioning and workholding applications in industrial, tooling, and fixture setups. The screw features a 1/4-20 UNC thread and measures 1 inch overall length with a 27/32-inch thread length. The pad swivels up to 7.5 degrees to maintain full surface contact on angled or uneven workpiece surfaces. The body and pad are constructed from alloy steel with a black oxide finish, which provides mild corrosion resistance and reduces light reflection in machine environments. Adjustment is made with a 1/8-inch hex key. Machinists, toolmakers, and fixture builders are the typical installers.

The SC328 is suited for use in jigs, fixtures, vises, and machine tool setups where a firm, adjustable support point is needed. The swivel pad design accommodates slight surface irregularities without concentrating load on a single edge, making it appropriate for securing workpieces that have machined or lightly contoured contact faces. The compact 1/4-20 thread size fits standard tooling plates and fixture bodies common in light-duty industrial environments.

Compatibility

Designed as a standard swivel pad leveling screw for use in industrial jigs, fixtures, and workholding assemblies with 1/4-20 UNC threaded mounting locations.

Installation Notes

Installation is typically performed by machinists or toolmakers using a 1/8-inch hex key. Ensure the mating threaded hole is clean and free of debris before threading in the screw. Verify the swivel pad moves freely before applying load. Do not exceed the rated load for the thread size, and do not use impact tools for installation as this may damage the swivel pad assembly.
