Gibraltar 34248SS Locking Plunger 5/8-11 Threaded Stud

Product Description

The GIBRALTAR 34248SS is a locking knob-style plunger with a threaded stud body, designed for use in indexing, positioning, and clamping applications across industrial and mechanical assemblies. The plunger features a 5/8-11 thread size with a 1 inch thread length and a maximum plunger diameter of 0.373 inches. Initial end force is 1.25 pounds, with a final end force of 5 pounds, providing a controlled spring-loaded holding action. The knobless threaded stud configuration allows flush or recessed installation where an external knob is not required. Stainless steel construction with a zinc-plated finish offers corrosion resistance in demanding environments. Licensed trade professionals and industrial MRO technicians are the typical installers.

The 34248SS is suited for use in fixtures, jigs, machine frames, and positioning assemblies where repeatable spring-loaded engagement is needed. The locking element locks the plunger in the retracted position, making it practical for applications requiring hands-free operation or repeated access to a work surface. The threaded stud body allows direct installation into tapped holes without an exposed knob above the mounting surface. This plunger is commonly found in manufacturing equipment, assembly fixtures, and mechanical enclosures.

Compatibility

Designed as a direct-install locking plunger for applications with a 5/8-11 tapped hole, compatible with fixtures, jigs, and mechanical assemblies requiring a knobless threaded stud plunger with locking capability.

Installation Notes

Installation requires a tapped 5/8-11 hole in the receiving assembly. Power down or de-energize any associated equipment before servicing or replacing plunger components in mechanical fixtures. Use appropriate thread-locking compound or torque to manufacturer specifications as dictated by the host assembly design. Do not exceed the rated final end force when compressing the plunger, as over-compression may damage the internal spring or locking element.
