Vlier FRT500P Locking T Handle Plunger 1/2-13 Steel

Product Description

The VLIER FRT500P is a locking T-handle plunger designed for precision positioning and retention applications in industrial and mechanical assemblies. Built with a steel body, this plunger uses a 1/2-13 thread and provides a plunger projection of 0.5 inches with a plunger diameter of 0.312 inches. The locking element engages to hold the plunger in the retracted position, allowing hands-free operation during setup or fixture changes. The T-handle design provides a secure grip for manual actuation without tools. Initial end force is 2.5 pounds, with a final end force of 5 pounds, making it suitable for moderate-duty hold and locate tasks in jigs, fixtures, and tooling setups.

The FRT500P is used in manufacturing, tooling, and assembly environments where repeatable manual positioning is required. It is commonly installed in fixture plates, machine guards, enclosures, and adjustable tooling frames. The 2.5-inch body length and 1.4-inch thread engagement provide solid mounting depth in standard steel plates. Licensed millwrights, machine builders, and fixture designers are the typical installers of this component.

Installation Notes

Install using standard hand tools appropriate for 1/2-13 threaded fasteners. Ensure the mounting plate or fixture has sufficient thread engagement depth to accommodate the 1.4-inch thread length. Isolate or de-energize any associated machinery before installing or removing the plunger assembly. Do not over-torque the body during installation, as this may damage the locking element or thread interface.
