Gibraltar 34260 Knob Handle Plunger 3/8-16 Threaded Stud

Product Description

The GIBRALTAR 34260 is a non-locking knob handle plunger with a threaded stud body, designed for use in industrial positioning, indexing, and tooling fixture applications. This plunger features a 3/8-16 inch external thread with a 0.75 inch thread length and a maximum plunger diameter of 0.216 inches. Spring end force ranges from 0.75 pounds initial to 4 pounds final, providing reliable retaining force for light-duty indexing tasks. The body is constructed from steel with a zinc-plated finish for corrosion resistance. Installed by machinists, tool and die makers, and maintenance technicians, this plunger fits standard threaded mounting holes in jigs, fixtures, and machine panels.

The GIBRALTAR 34260 is suited for light industrial and manufacturing environments where a compact, spring-loaded plunger is needed for panel mounting, fixture indexing, or component positioning. The threaded stud configuration allows direct installation into a tapped hole without a separate housing. The knobless design keeps the installed profile low, making it appropriate for confined or flush-mount locations where a protruding knob would interfere with adjacent components or moving parts.

Installation Notes

Installation requires a properly tapped 3/8-16 hole in the mounting panel or fixture body. De-energize or lock out any machinery before installing or replacing plungers in live equipment per applicable safety procedures. Use appropriate thread engagement depth to avoid bottoming out the stud and restricting plunger travel. A wrench flat or hex key may be required on the stud body depending on the specific mounting configuration.
