Vlier SSMD52P Threaded Spring Plunger 10-32 Stainless Steel

Product Description

The VLIER SSMD52P is a stubby threaded spring plunger designed for precise, repeatable positioning and detent applications in mechanical assemblies. It features a 10-32 thread with a 0.468-inch thread length and a 0.093-inch maximum plunger diameter, making it suited for compact installations where space is limited. The stainless steel body provides corrosion resistance, while the Delrin nose reduces wear on mating surfaces. A locking element is included to secure the plunger in place after installation. This part is installed by machinists, tool-and-die professionals, and mechanical assembly technicians working with precision fixtures, jigs, and indexing components.

The SSMD52P is used in applications requiring controlled spring force in a small footprint. The stubby plunger style fits installations with minimal clearance behind the threaded bore. With an initial end force of 1.75 pounds and a final end force of 6.25 pounds, it delivers a firm, consistent detent feel suited to light indexing, locking, and positioning tasks in industrial machinery, fixtures, and mechanical devices.

Key Features

• Stubby plunger style for compact, space-constrained installations
• 10-32 thread size with 0.468-inch thread and body length
• Stainless steel body for corrosion resistance in demanding environments
• Delrin nose material reduces wear on contact surfaces
• Locking element included to prevent plunger from backing out after installation
• 1.75 pounds initial end force and 6.25 pounds final end force for consistent detent action

Compatibility

Designed as an OEM-style replacement or direct-fit spring plunger for mechanical assemblies, fixtures, and indexing mechanisms requiring a 10-32 threaded bore and a stubby plunger profile.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using a standard hex key or spanner tool appropriate for the 10-32 thread. De-energize or lock out any equipment before servicing assemblies that contain spring plungers. The locking element should be engaged after the plunger is threaded to the correct depth to prevent loosening under vibration. Do not overtighten, as this can damage the Delrin nose or distort the plunger body.
