Vlier SSMD52 Threaded Spring Plunger 10-32 Stainless

Product Description

The VLIER SSMD52 is a stubby threaded spring plunger designed for indexing, positioning, and light detent applications in mechanical assemblies. It features a 10-32 thread size with a 0.468-inch thread length and a maximum plunger diameter of 0.093 inches. The plunger projects 0.065 inches and delivers an initial end force of 1.75 pounds and a final end force of 6.25 pounds. The stainless steel body resists corrosion in demanding environments, while the Delrin nose provides smooth, low-friction plunger action. Machinists, assemblers, and maintenance technicians install this type of hardware in jigs, fixtures, tooling plates, and precision equipment enclosures.

The SSMD52 suits applications requiring repeatable positioning or light ball-detent-style retention in compact or space-constrained assemblies. Its stubby body profile makes it appropriate where thread engagement depth is limited. Typical install scenarios include tooling fixtures, instrument panels, enclosure latching, and light-duty indexing mechanisms in both industrial and commercial equipment. The 10-32 thread fits standard tapped holes in steel, aluminum, and plastic assemblies.

Key Features

• Stubby plunger body at 0.468 inches overall length for compact installations
• 10-32 threaded body for standard tapped-hole installation
• 1.75-pound initial end force and 6.25-pound final end force for light detent duty
• Stainless steel body construction for corrosion resistance
• Delrin nose material for smooth, low-friction plunger travel
• No locking element - allows field adjustment after installation

Compatibility

Designed as an OEM-style replacement or direct-install spring plunger for mechanical assemblies, tooling fixtures, and equipment requiring a 10-32 threaded spring plunger with a stubby body profile.

Installation Notes

Installation is performed by machinists or mechanical assemblers using a standard hex key or spanner tool sized for the plunger body. Thread the plunger into a clean, properly tapped 10-32 hole and torque only to finger-tight plus snug - do not overtighten, as the stainless body can gall in steel tapped holes. De-energize or lock out any assembly under load before servicing spring plungers in active fixtures or mechanisms.
