Vlier SSC333 Swivel Pad 5/16-18 Unc Stainless Steel

Product Description

The VLIER SSC333 is a stainless steel swivel pad designed for use in clamping, fixturing, and workholding applications. The pad swivels up to 7.5 degrees to compensate for minor surface irregularities, maintaining consistent contact pressure across angled or uneven workpiece surfaces. The 5/16-18 UNC thread allows straightforward integration into standard clamp screws and fixtures. Overall length is 1 inch, and the pad diameter is 0.25 inches. Both the pad and tip are constructed from stainless steel, providing corrosion resistance in wet or chemically active environments. Adjustment is made with a 5/32-inch hex key. This component is typically installed by machinists, toolmakers, and fixturing technicians.

The SSC333 is suited for precision fixturing setups in machine shops, manufacturing cells, and inspection fixtures. The swivel function is especially useful when clamping on cast surfaces, machined tapers, or parts where parallelism cannot be guaranteed. The stainless steel construction makes this pad appropriate for food-processing equipment fixtures, medical device assembly, and other environments where carbon steel hardware is not acceptable. The 5/16-18 UNC thread is a common size across a wide range of commercially available clamp screws and rest buttons.

Key Features

• 7.5-degree swivel angle accommodates angled and irregular workpiece surfaces
• Stainless steel pad and tip material for corrosion resistance in demanding environments
• 5/16-18 UNC thread for compatibility with standard fixturing hardware
• 0.25-inch pad diameter provides a defined contact point for controlled clamping force
• 5/32-inch hex key drive allows precise torque application with standard tooling
• Manufactured to ISO 9001 quality standards

Compatibility

Designed as an OEM-style replacement or upgrade component for fixturing assemblies using 5/16-18 UNC threaded clamp screws and rest button systems.

Installation Notes

Installation requires a 5/32-inch hex key. Ensure the mating clamp screw or threaded body is clean and free of debris before threading in the SSC333. Apply torque evenly and do not overtighten, as the swivel mechanism requires freedom of movement to function correctly. Verify swivel action is unrestricted after installation before placing the fixture into service.
