Gibraltar 34174 Non-locking Plunger 1/4-20 Stainless Steel

Product Description

The GIBRALTAR 34174 is a non-locking knob handle plunger with a threaded stud body, designed for use in indexing, positioning, and clamping applications across industrial and mechanical assemblies. It features a 1/4-20 thread size with a 0.5-inch thread length and a maximum plunger diameter of 0.124 inches. The spring-loaded plunger delivers an initial end force of 0.5 pounds and a final end force of 2.5 pounds, providing consistent, repeatable engagement. Constructed from stainless steel with a zinc finish, the 34174 is suited for environments where corrosion resistance and dimensional precision are required. Mechanical and industrial technicians are the primary installers of this component.

This plunger is typically used in machine tool fixtures, jigs, panel assemblies, and equipment enclosures where a spring-loaded detent or stop point is needed. The knobless threaded stud design allows the unit to be installed flush or recessed into a tapped hole, making it suitable for low-clearance applications. With a plunger projection of 0.125 inches and a plunger length of 1.062 inches, it fits compact assemblies where space is limited. The 10-32 stud thread accommodates standard mounting configurations in light industrial and precision mechanical applications.

Compatibility

Designed as an OEM-style replacement or direct-fit component for industrial fixtures, jigs, and mechanical assemblies that accept a 1/4-20 threaded spring plunger with a non-locking, knobless stud configuration.

Installation Notes

Installation is performed by mechanical or industrial maintenance technicians using standard hand tools. Thread the stud into a properly tapped 1/4-20 hole and tighten to secure the plunger body in position. Ensure the mating hole or detent for the plunger tip is aligned and free of debris before final assembly. De-energize or lock out any moving machinery before installing or removing spring plungers in live assemblies.
