Vlier SSM50 Threaded Spring Plunger 8-36 Stainless Steel

Product Description

The VLIER SSM50 is a stubby threaded spring plunger designed for applications where high end force is required in restricted or tight spaces. It features an 8-36 thread size with a body and thread length of 0.437 inches, a maximum plunger diameter of 0.07 inches, and a plunger projection of 0.052 inches. Both the body and nose are constructed from stainless steel, providing corrosion resistance in demanding environments. Initial end force is 1.5 pounds, with a final end force of 4.75 pounds. This plunger is typically installed by machinists, toolmakers, or mechanical assemblers in precision equipment, fixtures, and mechanical assemblies requiring reliable spring-loaded positioning or detent action.

The SSM50 is suited for use in compact mechanical assemblies, jigs, fixtures, and industrial equipment where space constraints prevent the use of standard-length spring plungers. Its stubby body profile makes it an appropriate choice for shallow-threaded bores or confined housings. The high end force rating relative to its small size makes it effective in positioning, indexing, and detent applications across light industrial and precision manufacturing environments.

Key Features

• Stubby plunger length type for use in restricted-space applications
• 8-36 thread size with 0.437 inches thread and body length
• Stainless steel body and nose for corrosion resistance
• 1.5 pounds initial end force and 4.75 pounds final end force
• 0.052 inches plunger projection with 0.07 inches maximum plunger diameter
• No locking element, allowing straightforward threaded installation and adjustment

Compatibility

Designed as an OEM-style replacement or direct-install threaded spring plunger for precision fixtures, jigs, and mechanical assemblies requiring an 8-36 threaded bore with a stubby body profile.

Installation Notes

Installation is performed by machinists or mechanical assemblers using standard hand tools appropriate for small threaded fasteners. Ensure the receiving bore is clean and correctly tapped to 8-36 specifications before installation. Do not overtighten, as this may damage the small-diameter threads or restrict plunger travel. Confirm plunger projection and end force requirements are met after installation before placing the assembly into service.
