Vlier SC345 Swivel Pad 1/2-13 Unc 1 in Alloy Steel

Product Description

The VLIER SC345 is a swivel pad leveling foot designed for precision clamping and workholding applications. It features a 1/2-13 UNC thread and a 1 inch overall length, making it a compact solution for adjustable support in fixturing, jigs, and machine setups. The pad and tip are constructed from alloy steel with a black oxide finish, providing corrosion resistance and durability under repeated load. The 7.5-degree swivel angle allows the pad face to self-align against angled or uneven workpiece surfaces, reducing point loading and improving contact. A 1/4 inch hex key socket enables precise torque-in adjustment in tight clearances. This part is typically installed by machinists, toolmakers, and maintenance technicians.

The SC345 is suited for use in machine tool fixtures, assembly jigs, vises, and general industrial workholding setups where a rigid yet self-aligning contact point is required. The 0.4 inch pad diameter concentrates clamping force across a controlled contact area, and the 11/16 inch thread engagement length provides adequate holding strength for light-to-medium duty applications. The black oxide finish is appropriate for indoor industrial environments.

Key Features

• 7.5-degree swivel angle for self-alignment on angled or irregular surfaces
• Alloy steel pad and tip construction with black oxide finish for corrosion resistance
• 1/2-13 UNC thread standard for broad fixture and tooling compatibility
• 0.4 inch pad diameter for controlled contact area under clamping load
• 1/4 inch hex key drive for adjustment in confined spaces
• Manufactured under ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixturing, jigs, and machine tool setups requiring a 1/2-13 UNC threaded swivel pad leveling foot.

Installation Notes

Installation is performed by machinists or maintenance technicians using a 1/4 inch hex key. Secure the threaded body into the fixture or support block before applying load. Ensure the mating threaded bore is clean and free of debris to achieve full thread engagement across the 11/16 inch thread length. Do not exceed the load rating of the parent fixture assembly when applying clamping force.
