Gibraltar SSW10-4A-PT-G Threaded Spring Plunger 1/4-20

Product Description

The GIBRALTAR SSW10-4A-PT-G is a standard threaded spring plunger with a 1/4-20 thread size and a 1 inch thread length. It features a stainless steel body and nose with an integrated locking element to resist loosening from vibration or movement. The plunger diameter measures 0.118 inches with a 3/16 inch projection. Initial end force is 1 pound and final end force is 4 pounds. This type of component is installed by machinists, toolmakers, maintenance technicians, and mechanical assembly professionals in fixtures, jigs, and mechanical assemblies where controlled spring-loaded positioning is required.

This spring plunger is suited for use in precision positioning fixtures, machine tooling, automation equipment, and industrial assemblies where a repeatable, spring-loaded contact point is needed. The locking element secures the plunger body in the tapped hole, preventing rotation or backing out under load or vibration. It is appropriate for both light-duty and moderate-force indexing applications across industrial and manufacturing environments.

Key Features

• 1/4-20 thread size with 1 inch thread length for standard tapped hole installation
• Stainless steel body and nose for corrosion resistance in demanding environments
• Integrated locking element prevents loosening under vibration or dynamic loads
• 3/16 inch plunger projection provides controlled spring-loaded contact
• 1 pound initial end force and 4 pound final end force for light-to-moderate indexing applications
• Standard plunger length type for straightforward drop-in replacement or new installation

Compatibility

Designed as an OEM-style replacement or new-installation component for standard 1/4-20 tapped hole applications in fixtures, jigs, and mechanical assemblies requiring spring-loaded plunger positioning.

Installation Notes

Installation requires a properly tapped 1/4-20 through or blind hole in the mating component. Thread engagement should be sufficient to fully seat the locking element and prevent body rotation. De-energize or lock out any powered equipment before servicing assemblies containing spring plungers. Use a hex key or appropriate wrench on the body flats where provided to avoid damaging the plunger nose or locking element during installation.
