Gibraltar SW10-12-PT-G Threaded Spring Plunger 3/4-10

Product Description

The GIBRALTAR SW10-12-PT-G is a threaded spring plunger designed for positioning, locating, and indexing applications in industrial and mechanical assemblies. It features a 3/4-10 thread size with a 1-3/4 inch thread length and a standard-length steel body. The plunger projects 5/16 inch (0.3125 inch decimal) with a maximum plunger diameter of 0.374 inch. A locking element is included to secure the plunger in place after installation. Initial end force is 6.7 pounds and final end force is 37.3 pounds, making this part suitable for moderate-duty hold and release applications. Both the body and nose are steel construction.

This spring plunger is suited for use in machine tools, fixtures, jigs, and automated assembly equipment where repeatable positioning or detenting is required. The threaded body allows direct installation into a tapped hole, and the locking element prevents the plunger from backing out under vibration or repeated cycling. Typical applications include CNC fixturing, conveyor tooling, and general industrial machinery where a reliable mechanical stop or index point is needed. Licensed machinists and tool-and-die technicians are the primary installers.

Compatibility

Designed as an OEM-style replacement or direct-install threaded spring plunger for industrial fixtures, jigs, and mechanical assemblies requiring a 3/4-10 tapped hole.

Installation Notes

Installation is performed by machinists or mechanical technicians using a spanner wrench or appropriate hex tool. Ensure the receiving bore is tapped to 3/4-10 specification and is clean and free of debris before threading in the plunger. Engage the locking element fully to prevent loosening during operation. De-energize or lock out any machinery before servicing or replacing spring plunger components per applicable safety standards.
