Gibraltar SW10-4SL-PT Threaded Spring Plunger 1/4-20 Steel

Product Description

The GIBRALTAR SW10-4SL-PT is a stubby threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. It uses a 1/4-20 thread and delivers an initial end force of 1 pound, rising to a final end force of 3.5 pounds at full compression. The steel body and steel nose provide durability in industrial and trade environments. At 0.531 inches in thread length and a maximum plunger diameter of 0.119 inches, this is a compact, precise component suited for tight-tolerance installations. A built-in locking element prevents the plunger from backing out under vibration or repeated cycling, making it reliable in demanding service conditions.

This spring plunger is used in mechanical fixtures, jigs, tooling plates, and equipment panels where a repeatable spring-loaded detent or stop is required. The stubby plunger length and small projection of 0.078 inches make it well suited for shallow-depth applications where standard-length plungers would conflict with adjacent components. Machinists, maintenance technicians, and equipment assemblers commonly install this type of component during fabrication or field service of industrial machinery and trade equipment.

Key Features

• 1/4-20 thread for straightforward installation in tapped holes
• Stubby plunger profile with 0.531 inch thread length fits shallow assemblies
• Initial end force of 1 pound and final end force of 3.5 pounds for light-duty detent applications
• Steel body and steel nose construction for durability in industrial use
• Locking element prevents backing out under vibration or repeated loading cycles
• Low-profile 0.078 inch plunger projection minimizes interference with adjacent parts

Compatibility

Designed as a standard threaded spring plunger for use in any tapped 1/4-20 hole requiring a spring-loaded indexing or detent function in mechanical assemblies and industrial fixtures.

Installation Notes

Installation requires a properly tapped 1/4-20 hole to the correct depth to achieve full thread engagement. Use an appropriate driver or hex key on the locking element to seat the plunger and prevent rotation once positioned. Ensure the assembly is de-energized and depressurized before servicing any equipment that houses this component. Do not overtighten, as this can deform the plunger body and affect spring performance.
