Vlier DSSB50AP Threaded Ball Plunger 8-32 Stainless Steel

Product Description

The VLIER DSSB50AP is a threaded ball plunger designed for precise, repeatable positioning and detent applications in mechanical assemblies. It features an 8-32 thread, a stainless steel body with a zinc-plated finish, and a nylon ball with a diameter of 0.094 inches. The body length is 0.344 inches, and the maximum ball reach is 0.025 inches. With an initial end force of 0.50 pounds and a final end force of 1.25 pounds, this plunger delivers controlled, consistent spring-loaded engagement. A locking element is included to secure the plunger position after installation. Machinists, toolmakers, and precision assembly technicians are the typical installers.

This ball plunger is suited for use in jigs, fixtures, tooling plates, and light-duty mechanical indexing applications where a small-diameter threaded plunger is required. The nylon ball minimizes marring on contact surfaces, making it appropriate for applications where part finish protection is a concern. The 8-32 thread size fits standard tapped holes found in aluminum, steel, and plastic components commonly encountered in industrial and manufacturing settings.

Key Features

• 8-32 thread size for compatibility with standard tapped holes
• Stainless steel body with zinc-plated finish for corrosion resistance
• Nylon ball protects contact surfaces from marring or scratching
• Locking element secures plunger position after installation
• Initial end force of 0.50 pounds and final end force of 1.25 pounds for controlled detent engagement
• Compact 0.344 inch body length suits tight-clearance assemblies

Compatibility

Designed as a direct-fit threaded ball plunger for standard 8-32 tapped holes in jigs, fixtures, tooling plates, and mechanical indexing assemblies requiring a spring-loaded detent element.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 8-32 hole using an appropriate driver or hex key on the body flats. Ensure the mating hole is clean and free of debris before installation. The locking element should be engaged after the plunger is set to the desired depth to prevent loosening under vibration. Avoid overtightening, as this can damage the nylon ball or deform the body.
