Vlier S49P Threaded Spring Plunger 6-32 Steel Locking

Product Description

The VLIER S49P is a threaded spring plunger designed for precise, repeatable positioning and light-duty retention in mechanical assemblies. It features a 6-32 thread size with a 17/32 inch thread length and a standard-length steel body. The plunger nose diameter ranges from 0.044 to 0.045 inches, with a 1/16 inch projection beyond the mounting surface. Initial end force is 0.5 pounds and final end force is 1.5 pounds. A locking element is included to secure the plunger in place after installation. This part is installed by machinists, maintenance technicians, and mechanical assemblers working on precision equipment, fixtures, and tooling.

The S49P is suited for use in mechanical fixtures, jigs, tooling plates, and light industrial assemblies where controlled spring force and positive locking are required. It is commonly installed in tapped holes in steel, aluminum, or similar materials where a flush or near-flush spring-loaded retention point is needed. The compact 6-32 thread size makes it appropriate for small-scale mechanical components and tight-clearance applications.

Key Features

• 6-32 thread size with 17/32 inch thread length for standard tapped-hole installation
• Plunger projection of 1/16 inch for low-profile retention
• Initial end force of 0.5 pounds and final end force of 1.5 pounds for light-duty positioning
• Plunger nose diameter 0.044 to 0.045 inches for precise fit
• Steel body and steel nose material for durability in industrial environments
• Integrated locking element secures plunger position after adjustment

Compatibility

Designed as an OEM-style replacement or direct-install spring plunger for mechanical assemblies using a 6-32 tapped hole and requiring a standard-length threaded spring plunger with locking element.

Installation Notes

Installation is performed by qualified mechanical assemblers or maintenance technicians using a standard hex key or spanner tool appropriate for the plunger body style. Ensure the receiving tapped hole is clean and free of debris before threading in the plunger. Torque the body to the point where the locking element engages without damaging the thread or plunger nose. De-energize or lock out any equipment the assembly is mounted in before servicing spring plungers in live fixtures or tooling.
