Gibraltar 34171 Non-locking Plunger 5/8-11 Thread

Product Description

The GIBRALTAR 34171 is a non-locking knob handle plunger with a threaded stud body and no attached knob, designed for use in positioning, clamping, and indexing applications across industrial and mechanical assemblies. It features a 5/8-11 thread size with 1 inch of thread length and a maximum plunger diameter of 0.311 inches. The plunger delivers an initial end force of 5 pounds and a final end force of 10 pounds, providing positive, repeatable engagement. Constructed from stainless steel with a zinc-plated finish, this plunger is suited for environments where corrosion resistance and dimensional precision are required. It is installed by maintenance technicians, machinists, and mechanical assemblers.

The GIBRALTAR 34171 is appropriate for use in fixtures, jigs, machine tooling, and industrial equipment where a compact, threaded-stud plunger is needed for spring-loaded positioning or retention. The knobless design allows integration into assemblies where a flush or recessed mount is required. A locking element is included. The stud thread size is 1/2-13, and the length under head/shoulder is 0.312 inches. Plunger projection measures 0.3125 inches, and total plunger length is 2.186 inches.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using standard hand tools. Ensure the mating threaded bore is clean and free of debris before threading the plunger into place. Power down or de-energize any associated equipment before servicing assemblies that incorporate this plunger. Do not exceed the rated end force range, as overloading the spring mechanism can cause premature wear or failure.
