Vlier FRT500 Locking T Handle Plunger 1/2-13 Thread Steel

Product Description

The VLIER FRT500 is a locking T-handle spring plunger designed for industrial positioning, indexing, and locking applications. The plunger body is machined from steel and features a 1/2-13 thread for secure installation into threaded housings or fixtures. With a 2.5 inch body length and a 5/16 inch plunger diameter, this unit delivers a 2.5 pound initial end force and a 5 pound final end force, making it well suited for repeatable detent and locking work. Maintenance technicians and machine builders install this type of plunger in jigs, fixtures, and production equipment where a positive, hand-operated lock is required.

The FRT500 is used in light industrial and manufacturing environments where operators need a reliable manual locking mechanism. The T-handle design allows tool-free hand operation, and the 2 inch handle length provides adequate leverage for engagement and release. A 1.4 inch thread length gives sufficient engagement depth for most standard fixture applications. The 0.5 inch plunger projection provides the travel needed for typical detent or stop applications in jigs, fixtures, and machine slides.

Installation Notes

Installation is performed by threading the FRT500 body into a pre-tapped 1/2-13 hole in the fixture or housing. Ensure the receiving hole is clean and free of debris before installation. De-energize or lock out any machinery before servicing or replacing plunger components. Do not exceed the rated end force values when selecting this plunger for load-bearing detent applications.
