Gibraltar 34238SS Locking Plunger 3/8-16 Stainless Steel

Product Description

The GIBRALTAR 34238SS is a locking knob-style plunger with a threaded stud configuration designed for precise positioning and retention in industrial fixtures, jigs, and mechanical assemblies. Built from stainless steel with a zinc-plated finish, this plunger delivers an initial end force of 1.5 pounds and a final end force of 8 pounds, providing firm, repeatable locking engagement. The 3/8-16 thread size and 0.75-inch thread length allow straightforward installation into tapped holes. Mechanical technicians and tooling specialists install this type of component in workholding, machine guarding, and adjustable panel applications where a knobless, flush-mount profile is required.

This plunger is suited for use in light to medium-duty industrial applications where a locking plunger with a threaded stud body is needed. The knobless design keeps the profile low, making it appropriate for recessed or space-constrained mounting points in machine frames, fixtures, and enclosures. The stainless steel construction offers corrosion resistance in wash-down or high-humidity environments. Sold individually, it fits installations requiring a single-piece replacement or new assembly component.

Installation Notes

Installation is performed by mechanical technicians or tooling specialists using standard hand tools. Power down or de-energize any associated machinery before servicing plunger assemblies. Thread the stud into a properly tapped 3/8-16 hole and verify locking engagement before returning equipment to service. Do not exceed the rated end force or modify the plunger body.
