Gibraltar 34144 Non-locking Plunger 1/4-20 Steel Zinc

Product Description

The GIBRALTAR 34144 is a non-locking knob handle plunger with a threaded stud body and no attached knob, designed for light-duty positioning and indexing applications in industrial and mechanical assemblies. Built from steel with a zinc finish, it features a 1/4-20 external thread with a 0.5-inch thread length, a maximum plunger diameter of 0.124 inches, and a plunger projection of 0.125 inches. The spring mechanism delivers 1 pound of initial end force and 5 pounds of final end force. A licensed mechanic, millwright, or MRO technician typically installs this type of component in fixtures, jigs, or enclosures where repeatable detent action is required.

The GIBRALTAR 34144 fits applications that require a compact, spring-loaded plunger in panel-mount or through-hole assemblies. The threaded stud style allows direct installation into tapped holes without a separate mounting flange, making it well suited for thin panels and tight clearance installations. The stud carries a secondary 10-32 thread, extending its use in multi-fastener configurations. This plunger is used across manufacturing, tooling, and general mechanical assembly environments.

Key Features

• Non-locking plunger action with 1 pound initial end force and 5 pounds final end force
• Threaded stud body (knobless) with 1/4-20 external thread and 0.5-inch thread length
• Secondary stud thread size of 10-32 for versatile mounting configurations
• Maximum plunger diameter of 0.124 inches with a diameter tolerance of plus 0.001 inches
• Plunger projection of 0.125 inches and overall plunger length of 1.062 inches
• Steel construction with zinc finish for corrosion resistance in general-duty environments

Compatibility

Designed as an OEM-style replacement or new-install plunger for industrial fixtures, jigs, enclosures, and mechanical assemblies requiring a 1/4-20 threaded non-locking spring plunger.

Installation Notes

Install into a tapped 1/4-20 hole using a wrench applied to the stud flats; do not over-torque, as the steel body can strip thin panel threads. Power down or de-energize any associated equipment before servicing assemblies containing this plunger. Ensure the mating hole is free of debris and the thread engagement depth matches the 0.5-inch thread length for full holding strength.
