Gibraltar 34236 Locking Knob Plunger 1/4-20 Steel

Product Description

The GIBRALTAR 34236 is a locking knob-style plunger with a threaded stud body and no external knob, designed for indexing and positioning applications in mechanical assemblies. It features a 1/4-20 thread size with a thread length of 0.5 inches and a maximum plunger diameter of 0.144 inches. The spring-loaded steel plunger delivers an initial end force of 1 pound and a final end force of 5 pounds, making it suited for light-duty hold and release applications. A locking element retains the plunger in the retracted position when needed. The zinc-plated steel construction resists corrosion in typical shop and industrial environments. Machinists, millwrights, and mechanical technicians install this type of component during machine setup, fixture building, or panel assembly work.

The GIBRALTAR 34236 fits into threaded bores in machine frames, jigs, fixtures, and enclosures where a low-profile, knobless plunger is required. The threaded stud design allows flush or near-flush installation in panels or housings where a projecting knob would interfere with adjacent components or covers. The 5/8-inch length under head and 0.125-inch plunger projection suit applications requiring minimal protrusion beyond the mounting surface. This part is sold individually and is appropriate for both original equipment builds and replacement service on existing assemblies.

Key Features

• Locking plunger element holds plunger in retracted position during setup or part loading
• 1/4-20 external thread with 0.5-inch thread length for standard threaded bore installation
• Threaded stud style without knob for low-profile, flush-panel mounting
• Steel construction with zinc-plated finish for corrosion resistance
• Initial end force of 1 pound, final end force of 5 pounds for light-duty indexing
• Stud thread size 10-32 for secure body retention in the mating component

Compatibility

Designed as a direct-fit replacement or original-equipment locking plunger for mechanical assemblies, fixtures, jigs, and enclosures that accept a 1/4-20 threaded plunger with a knobless threaded stud body.

Installation Notes

Installation is performed by machinists or mechanical technicians using standard hand tools. Thread the plunger body into the prepared 1/4-20 tapped bore and tighten to the assembly specification for the host fixture. De-energize or fully power down any machine or assembly before servicing or replacing plunger components. Do not exceed the rated end force by using the plunger in applications requiring higher spring loads than the 5-pound final end force rating.
