Gibraltar 34161 Knob Handle Plunger 5/8-11 1 in Thread

Product Description

The GIBRALTAR 34161 is a non-locking knob handle plunger with a threaded stud body and no knob installed, designed for use in indexing, positioning, and clamping applications across industrial and mechanical assemblies. Built from steel with a zinc finish, this plunger features a 5/8-11 thread size with a 1 inch thread length and a stud thread size of 1/2-13. It delivers an initial end force of 3 pounds and a final end force of 6 pounds, making it well suited for light-duty holding and locating tasks. The plunger diameter is 0.311 inches with a tolerance of plus 0.001 inches. Machinists, millwrights, and maintenance technicians are the typical end users for this type of hardware.

The GIBRALTAR 34161 fits into threaded housings or fixtures where a spring-loaded plunger is needed to index or retain a moving component. The knobless threaded stud design allows the plunger to be installed flush or recessed into a panel or housing, with a separate actuator added at the installer's discretion. A locking element is included. The plunger projection of 5/16 inches and a head height of 7/16 inches support compact installation envelopes. This part is sold individually and is appropriate for light industrial machinery, jigs, fixtures, and equipment enclosures.

Installation Notes

This plunger is installed by threading it into a pre-tapped hole sized for a 5/8-11 thread. Ensure the receiving housing is properly tapped and free of debris before installation. Use appropriate hand tools and do not overtighten, as this may affect plunger travel and end force performance. Verify plunger projection and thread engagement meet the requirements of the assembly before finalizing installation.
