Gibraltar SWN10-4SL-PT-G Threaded Spring Plunger 1/4-20

Product Description

The GIBRALTAR SWN10-4SL-PT-G is a stubby threaded spring plunger designed to provide controlled, spring-loaded positioning and detent action in mechanical assemblies. The steel body threads into a tapped hole using a standard 1/4-20 thread, with a thread length of 0.531 inches and a maximum plunger diameter of 0.119 inches. The nylon nose projects 0.078 inches and delivers an initial end force of 1 pound, building to a final end force of 3.5 pounds. A locking element is integrated into the body to prevent the plunger from backing out under vibration. Machinists, tool-and-die techs, and mechanical assemblers commonly install this type of component in fixtures, jigs, and precision positioning equipment.

This spring plunger suits applications where repeatable, low-force detent or positioning action is needed in a compact envelope. The stubby body profile makes it appropriate for shallow installations or tight panel depths where a standard-length plunger body will not fit. Typical use cases include machine tool fixtures, assembly jigs, tooling plates, and any mechanical subassembly requiring a spring-loaded indexing or retention point. The nylon nose reduces marring on contact surfaces, making it a practical choice where surface finish on mating parts must be preserved.

Key Features

• Stubby plunger length type suits shallow or space-constrained installations
• Steel body provides durable threading and structural integrity
• Nylon nose minimizes marring on mating or contact surfaces
• Integrated locking element prevents back-out under vibration
• 1/4-20 standard thread simplifies installation into common tapped holes
• Progressive spring force from 1 pound initial to 3.5 pounds final end force allows predictable detent action

Compatibility

Designed as an OEM-style threaded spring plunger for mechanical fixtures, jigs, tooling plates, and positioning assemblies that accept a 1/4-20 threaded spring plunger with a stubby body profile.

Installation Notes

Installation is performed by mechanical assemblers or machinists using a hex key or spanner wrench appropriate for the body style. The mating component must have a properly tapped 1/4-20 hole to the specified thread depth. Disengage or de-energize any powered equipment before installing or removing spring plungers in active assemblies. The locking element should be engaged to the manufacturer-specified torque range per standard mechanical fastener practice to prevent loosening during operation.
