Gibraltar SDKN25-PT-G Knob Handle Plunger 1/4-20

Product Description

The GIBRALTAR SDKN25-PT-G is a non-locking knob handle plunger with a 1/4-20 thread and a Delrin knob, designed for use in light-duty indexing, positioning, and panel-mounting applications. The plunger delivers an initial end force of 0.12 pounds and a final end force of 0.36 pounds, providing consistent spring tension for repeatable positioning tasks. The body measures 0.63 inches in length with a thread length of 0.50 inches and a maximum plunger diameter of 0.16 inches. Machinists, fabricators, and equipment assemblers typically install this type of plunger in jigs, fixtures, enclosures, and light machinery where tool-free hand adjustment is required.

This plunger is suited for use in industrial equipment panels, machine tool fixtures, enclosures, and assembly jigs where a compact, hand-operable indexing point is needed. The non-locking plunger design allows the spring-loaded tip to retract and re-engage without a separate release mechanism, making it well suited for frequent adjustment cycles. Its compact overall profile fits in tight panel or frame installations where space is limited.

Key Features

• Non-locking spring-loaded plunger for tool-free hand adjustment

Compatibility

Designed as an OEM-style replacement or direct-install component for standard 1/4-20 tapped-hole applications in jigs, fixtures, enclosures, and light industrial equipment panels.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped 1/4-20 hole by hand or with a wrench applied to the hex flat. Ensure the mating hole is clean and threads are free of debris before installation. Avoid over-torquing, as the Delrin knob and body are not rated for high-torque mechanical fastening. Confirm plunger travel and spring engagement before returning the assembly to service.
