Vlier SSC347 Swivel Pad Leveling Screw 1/2-13 Unc

Product Description

The VLIER SSC347 is a swivel pad leveling screw designed for precision positioning and workholding applications in industrial and mechanical assemblies. Built entirely from stainless steel, this fastener features a 1/2-13 UNC thread and a 7.5-degree swivel angle that allows the pad to self-align against non-flat or angled surfaces, distributing load evenly and reducing point stress. Overall length is 2 inches with a thread length of 1-11/16 inches. The 0.4-inch diameter stainless pad and 1/4-inch hex key drive make it suitable for controlled torque installation in tight clearances. Machinists, toolmakers, and millwrights typically specify this type of component for fixturing, jig builds, and machine leveling.

The SSC347 is appropriate for use in both light industrial and precision manufacturing environments where corrosion resistance and reliable surface contact are required. The stainless steel pad and body construction make it suitable for washdown environments, food-grade adjacent applications, and settings where mild chemical exposure is expected. It is driven with a standard 1/4-inch hex key, which is common tooling on most shop floors and service vehicles.

Key Features

• 7.5-degree swivel angle allows pad self-alignment on angled or uneven mating surfaces
• Full stainless steel construction for corrosion resistance in demanding environments
• 1/2-13 UNC thread standard for broad compatibility with standard tapped holes
• 0.4-inch pad diameter distributes clamping or leveling load over contact area
• 1/4-inch hex key drive for installation in confined spaces
• Manufactured under ISO 9001 quality management standards

Compatibility

Designed as a direct-fit swivel pad leveling screw for any application using a standard 1/2-13 UNC tapped hole, including jigs, fixtures, machine bases, and leveling assemblies requiring a self-aligning pad tip.

Installation Notes

Installation is performed by threading the SSC347 into a 1/2-13 UNC tapped hole using a 1/4-inch hex key. Ensure the mating thread is clean and free of debris before installation. Do not exceed the load rating of the assembly or apply torque beyond what the hex key drive is rated to accept. In machine leveling applications, always power down and lock out the equipment before making height or position adjustments.
