Vlier SSM50P Threaded Spring Plunger 8-36 Stainless Steel

Product Description

The VLIER SSM50P is a threaded spring plunger designed for precise, repeatable positioning and locking in space-constrained assemblies. Built with a stainless steel body and stainless steel nose, this stubby-style plunger uses an 8-36 thread and delivers an initial end force of 1.5 pounds and a final end force of 4.75 pounds. The integrated locking element holds the plunger securely against unintended back-out under vibration or load. With a thread and body length of 0.437 inches and a maximum plunger diameter of 0.07 inches, it is engineered for applications where axial space is limited and reliable end force is required.

The SSM50P is well suited for use in precision mechanical assemblies, tooling fixtures, automation equipment, and similar applications where restricted space prevents the use of standard-length plungers. Its high end force rating relative to its compact size makes it appropriate for indexing, detent, and light clamping functions in both OEM manufacturing and field service environments. Technicians and assemblers working with small-format hardware in close-tolerance designs will find this plunger a direct fit for high end force, restricted space scenarios.

Key Features

• Stubby plunger length type for use in restricted-space assemblies
• Stainless steel body and nose for corrosion resistance and durability
• Integrated locking element resists back-out under vibration and dynamic loading
• 1.5 pound initial end force and 4.75 pound final end force for reliable detent action
• 8-36 thread size with 0.437 inch thread length for secure, compact installation
• Maximum plunger diameter of 0.07 inches suits fine-tolerance bores

Compatibility

Designed as an OEM-style threaded spring plunger for high end force, restricted-space applications requiring an 8-36 thread and stubby body format.

Installation Notes

Installation is typically performed by machine assemblers or maintenance technicians using a hex key or driver matched to the plunger body. Ensure the mating threaded hole is clean and within tolerance before installation to avoid cross-threading the fine 8-36 thread. The locking element should be engaged fully to prevent loosening during operation. De-energize or lock out any powered equipment before servicing assemblies that contain this plunger.
