Vlier SSS50P Threaded Spring Plunger 8-32 Stainless Steel

Product Description

The VLIER SSS50P is a threaded spring plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The plunger body and nose are both stainless steel construction, making it suitable for corrosion-resistant installations. It uses an 8-32 thread with a body and thread length of 5/8 inches. The plunger nose diameter ranges from 0.069 to 0.070 inches with a 3/32 inch projection. Initial end force is 2.7 pounds and final end force is 7.3 pounds. A locking element is included to secure the plunger in the threaded bore after installation. This part is installed by machinists, toolmakers, and mechanical assembly technicians.

The SSS50P is suited for use in precision mechanical fixtures, jigs, tooling plates, and production machinery where repeatable positioning or soft detent action is required. The standard plunger length type and compact 8-32 thread size make it appropriate for applications with limited space. The stainless steel body supports use in environments where mild corrosion resistance or cleanroom-compatible materials are required. Typical applications include panel assemblies, sliding components, rotating mechanisms, and any assembly requiring a spring-loaded retaining or locating function.

Key Features

• Stainless steel body and nose for corrosion resistance
• 8-32 thread size with 5/8 inch thread and body length
• Plunger projection of 3/32 inch for precise detent depth
• Initial end force of 2.7 pounds and final end force of 7.3 pounds
• Locking element secures plunger position after adjustment
• Compact nose diameter of 0.069 to 0.070 inches for tight-tolerance bores

Compatibility

Designed as a standard 8-32 threaded spring plunger for use in any tapped bore accepting 8-32 threads where a spring-loaded plunger with locking element is required.

Installation Notes

Installation requires a properly tapped 8-32 threaded hole in the receiving component. Use an appropriate driver or spanner tool to seat the plunger and engage the locking element to prevent back-out under vibration. Ensure the bore depth accommodates the full 5/8 inch body length before installation. Verify plunger projection and force requirements against the application before final assembly.
