Vlier SSS52 Threaded Spring Plunger 10-32 Stainless Steel

Product Description

The VLIER SSS52 is a threaded spring plunger designed to provide controlled, repeatable positioning force in mechanical assemblies. The stainless steel body and nose resist corrosion and wear in demanding environments. The plunger uses a 10-32 thread and has a 3/4 inch thread length, allowing straightforward installation into tapped holes. It delivers an initial end force of 2.9 pounds and a final end force of 11.1 pounds, making it suitable for applications requiring a firm, consistent detent or positioning action. Machinists, tool-and-die technicians, and precision assembly workers typically specify this component for jigs, fixtures, and production tooling.

The SSS52 is used in precision mechanical assemblies where a spring-loaded plunger must engage a detent, register a part, or hold a component in position under controlled spring force. The standard plunger projection of 1/8 inch suits applications with limited clearance. The all-stainless steel construction makes it appropriate for cleanroom, food-processing, or corrosion-sensitive environments where carbon steel or brass body plungers are not acceptable.

Key Features

• 10-32 thread size with 3/4 inch thread length for installation into standard tapped holes
• Stainless steel body and nose for corrosion resistance and long service life
• 2.9 pound initial end force and 11.1 pound final end force for reliable detent action
• 1/8 inch plunger projection for use in tight-clearance assemblies
• Standard plunger length type for straightforward drop-in replacement
• No locking element - free-spinning installation for fast assembly and adjustment

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies, jigs, and fixtures requiring a 10-32 threaded spring plunger with standard 3/4 inch body length.

Installation Notes

Installation is performed by threading the SSS52 into a properly tapped 10-32 hole using a hex key or slotted driver appropriate for the drive type. Ensure the mating hole is tapped to the correct depth to achieve full thread engagement across the 3/4 inch thread length. De-energize or mechanically lock any moving assembly before installing or removing plungers in active tooling. Do not exceed the rated final end force by over-compressing the plunger, as this may damage the internal spring.
