Gibraltar SSW10-4-PT-G Threaded Spring Plunger 1/4-20

Product Description

The GIBRALTAR SSW10-4-PT-G is a threaded spring plunger designed for indexing, positioning, and light detent applications in mechanical assemblies. The body is constructed from stainless steel, providing corrosion resistance in demanding environments. This plunger features a 1/4-20 thread with a 1 inch thread length and a maximum plunger diameter of 0.118 inches, delivering a 3/16 inch projection. Initial end force is 3 pounds and final end force is 13 pounds. A locking element is included to secure the plunger position once set. Machinists, tool and die technicians, and maintenance professionals install these in jigs, fixtures, and production tooling.

This spring plunger is suited for use in industrial fixtures, assembly jigs, and mechanical positioning applications where repeatable detent force is required. The stainless steel body makes it appropriate for environments where mild corrosion resistance or cleanliness standards apply. The standard plunger length configuration fits common through-hole and tapped-bore mounting arrangements found in light manufacturing and machine tool applications.

Key Features

• 1/4-20 thread size with 1 inch thread length for standard tapped-bore installation
• Stainless steel body for corrosion resistance in industrial environments
• 3/16 inch plunger projection with 0.118 inch maximum plunger diameter
• 3 pound initial end force and 13 pound final end force for controlled detent action
• Locking element included to fix plunger setting after adjustment
• Standard plunger length type for broad fixture and tooling compatibility

Compatibility

Designed as an OEM-style replacement or direct-install threaded spring plunger for industrial fixtures, jigs, and mechanical assemblies requiring a 1/4-20 tapped bore.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 1/4-20 bore using a hex wrench sized for a 0.0781 inch hex. Ensure the mating bore is clean and free of debris before installation. Engage the locking element only after the plunger is set to the desired depth. No power source shutdown is required, but follow applicable facility lockout procedures if installing in powered machinery.
