Vlier SSB58N Threaded Ball Plunger 3/8-16 Stainless Steel

Product Description

The VLIER SSB58N is a threaded ball plunger designed for controlled end-force applications where a compact, lightweight spring-loaded device is required. It features a 3/8-16 threaded body measuring 0.625 inches in length with a 0.188-inch stainless steel ball and a maximum ball reach of 0.048 inches. Initial end force is 5 pounds, with a final end force of 10 pounds. Both the body and ball are constructed from stainless steel for corrosion resistance and durability. A locking element is included to secure the plunger in position once installed. This part is typically installed by mechanical assemblers, maintenance technicians, and precision equipment specialists.

The SSB58N is suited for use in positioning, indexing, and detent applications across industrial, mechanical, and light-duty assembly environments. Its small footprint and controlled force range make it appropriate for fixtures, jigs, tooling, and equipment panels where repeatable positioning and minimal space are priorities. The purple color code aids in visual identification during assembly and inventory management.

Key Features

• 3/8-16 thread size for standard threaded mounting
• Stainless steel body and ball for corrosion resistance
• 5-pound initial end force and 10-pound final end force for controlled detent action
• 0.048-inch maximum ball reach for precise, low-profile engagement
• Integrated locking element to hold plunger position after installation
• Compact design suited for space-constrained assemblies

Compatibility

Designed as a standard threaded ball plunger for use in positioning, indexing, and detent applications requiring a 3/8-16 threaded mount and controlled spring-loaded end force.

Installation Notes

Installation is typically performed by mechanical technicians or assemblers using standard hand tools. Ensure the mating threaded bore is clean and dimensionally correct for a 3/8-16 thread before installation. Apply appropriate thread locking compound or torque per equipment manufacturer specifications if the locking element alone is insufficient for the application. De-energize or fully secure any equipment before servicing spring-loaded plunger components to prevent unintended movement.
