Vlier SSS53P Threaded Spring Plunger 10-32 Stainless Steel

Product Description

The VLIER SSS53P is a threaded spring plunger designed for locating, positioning, and indexing applications in mechanical assemblies. It features a stainless steel body with a locking element that secures the plunger in place once installed. The 10-32 thread size and 3/4 inch thread length make it suitable for use in standard threaded holes. The plunger tip measures 0.092 inches in diameter with a 1/8 inch projection. Initial end force is 1.3 pounds and final end force is 2.7 pounds, providing consistent, repeatable positioning force across the travel range. Machinists, toolmakers, and fixture builders are the typical installers of this component.

This spring plunger is used in workholding fixtures, jigs, tooling plates, and precision positioning assemblies where a small, repeatable detent or locating force is required. It fits applications where the plunger must remain locked in its threaded bore without backing out under vibration or repeated cycling. Typical environments include machine shop fixtures, assembly line tooling, and industrial positioning components requiring reliable spring-loaded engagement in a compact form factor.

Key Features

• 10-32 thread size with 3/4 inch thread length for standard installation
• Stainless steel body for corrosion resistance in industrial environments
• Locking element prevents the plunger from backing out of the threaded bore
• 0.092 inch plunger tip diameter with 1/8 inch projection
• 1.3 pound initial end force and 2.7 pound final end force for defined positioning resistance

Compatibility

Designed as an OEM-style replacement or direct installation component for workholding fixtures, jigs, and positioning assemblies requiring a 10-32 threaded spring plunger with a locking element.

Installation Notes

Installation is performed by machinists or toolmakers using a standard hex key or spanner wrench appropriate to the plunger head style. Thread the SSS53P into a properly tapped 10-32 hole and torque per the fixture design requirements. De-energize or lock out any powered equipment before servicing assemblies that contain this plunger. Verify that the locking element is fully engaged and that the plunger moves freely through its full projection range before returning the fixture to service.
