Gibraltar 34022 Locking Plunger 1/4-20 0.5in Thread Steel

Product Description

The GIBRALTAR 34022 is a locking knob handle plunger with a threaded stud body and no knob, designed for use in indexing, positioning, and clamping applications across industrial and mechanical assemblies. Built from steel with a zinc-plated finish for corrosion resistance, this plunger features a 1/4-20 external thread with a 0.5-inch thread length and a stud thread size of 10-32. It delivers an initial end force of 1 pound and a final end force of 5 pounds, making it suitable for light-duty locking and positioning tasks. The locking element engages to hold the plunger in the retracted or extended position without requiring continuous manual pressure.

This plunger is used in industrial equipment, jigs, fixtures, and mechanical assemblies where a compact, threadable positioning device is needed. The knobless threaded stud design allows it to be installed flush or driven from a panel face, making it practical in tight clearance situations. It is a common component in machine tool fixtures, enclosures, and positioning brackets used by maintenance technicians and mechanical assemblers across light manufacturing and trade service environments.

Key Features

• Locking plunger type holds position without continuous manual force
• 1/4-20 external thread with 0.5-inch thread length for standard panel installation
• Knobless threaded stud body suits flush-mount and recessed applications
• Initial end force of 1 pound, final end force of 5 pounds for light-duty positioning
• Steel construction with zinc-plated finish for corrosion resistance
• Compact plunger projection of 0.125 inches minimizes interference in tight assemblies

Compatibility

Designed as a standard 1/4-20 threaded locking plunger for use in industrial fixtures, mechanical assemblies, and positioning equipment requiring a knobless threaded stud style plunger.

Installation Notes

Installation is performed by threading the stud into a tapped hole sized for 1/4-20 thread. Ensure the mating panel or bracket is tapped to the correct depth to achieve the specified thread engagement. Secure the plunger body with a wrench on the head flat surfaces to avoid over-torquing the stud threads. Verify the plunger projection and locking element function freely before placing the assembly into service.
