Vlier PH48P Threaded Spring Plunger 6-32 Steel Body

Product Description

The VLIER PH48P is a standard threaded spring plunger designed to provide repeatable positioning, indexing, and light-duty detent functions in mechanical assemblies. It features a 6-32 thread size with a 17/32 inch thread length and a steel body with a steel nose. The plunger delivers an initial end force of 1.5 pounds and a final end force of 4.5 pounds, with a middle end force of 3.0 pounds. The minimum plunger diameter is 0.044 inches and the maximum is 0.045 inches, with a projection of 1/16 inch. A locking element is included to secure the plunger in the threaded bore after installation. Machinists, tool-and-die technicians, and mechanical assemblers typically install this component.

The PH48P is suited for use in light-load indexing applications, fixture alignment, and panel or drawer detent mechanisms across industrial, tooling, and precision assembly environments. Its compact 6-32 thread makes it appropriate for small-bore tapped holes in metal frames, jigs, and fixtures where consistent spring force and positive retention are required. The steel body and steel nose construction support use in typical shop and production settings where moderate wear resistance is needed.

Key Features

• 6-32 thread size with 17/32 inch thread length for secure installation in tapped bores
• Steel body and steel nose construction for durability in industrial applications
• Initial end force of 1.5 pounds and final end force of 4.5 pounds for consistent detent action
• 1/16 inch plunger projection for low-profile positioning and indexing
• Locking element included to hold plunger position after adjustment
• Standard plunger length type for common fitment in threaded assemblies

Compatibility

Designed as an OEM-style replacement or direct-fit component for assemblies requiring a 6-32 threaded spring plunger with standard projection and a steel body.

Installation Notes

Installation is performed by threading the PH48P into a pre-tapped 6-32 bore using an appropriate hex driver sized to the 0.050 inch hex. De-energize or lock out any powered equipment before servicing assemblies that contain spring plungers. Use thread-locking compound or the integrated locking element as designed to prevent back-out under vibration. Do not overtighten, as excessive torque can damage the plunger mechanism or the surrounding bore threads.
