Gibraltar SKNL-1-G Knob Handle Spring Plunger 1/4-20

Product Description

The GIBRALTAR SKNL-1-G is a non-locking knob handle spring plunger with a knurled knob designed for indexing, positioning, and light-duty locking applications in industrial and mechanical assemblies. It features a 1/4-20 thread size with a 0.5-inch thread length and a stainless steel body measuring 0.79 inches in length. The plunger delivers an initial end force of 1 pound and a final end force of 4 pounds, making it well suited for applications requiring controlled, repeatable engagement force. Machinists, toolmakers, and maintenance technicians install this type of component in fixtures, jigs, enclosures, and panel assemblies.

This spring plunger is used in light industrial settings where a simple, hand-operable positioning device is needed. The knurled knob allows for tool-free operation, and the non-locking design permits smooth plunger retraction under load. Typical install scenarios include machine tool fixtures, enclosure panels, and assembly jigs where repeatable detent positioning is required. The stainless steel construction provides corrosion resistance for use in moderately demanding environments.

Compatibility

Designed as a standard 1/4-20 threaded spring plunger for use in any tapped hole application requiring a non-locking knob-style indexing plunger with matching thread and force specifications.

Installation Notes

Installation requires a properly tapped 1/4-20 hole in the mating component. Thread the plunger in by hand using the knurled knob, then snug to the desired seating depth. Ensure the plunger axis is aligned with the detent or indexing feature to avoid side loading the plunger tip. De-energize or lock out any moving equipment before servicing assemblies containing spring plungers.
