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

Product Description

The GIBRALTAR SSW10-4-G is a threaded spring plunger designed for use in positioning, indexing, and light-duty locking applications across industrial and mechanical assemblies. The plunger features a 1/4-20 thread with a 1 inch thread length and delivers an initial end force of 3 pounds, building to a final end force of 13 pounds at full compression. The stainless steel body resists corrosion in demanding environments, while the steel nose provides durability at the contact point. The maximum plunger diameter is 0.118 inches with a 3/16 inch projection. This component is typically installed by machinists, maintenance technicians, and assembly professionals working with fixtures, jigs, and mechanical housings.

The SSW10-4-G fits applications requiring a compact, standard-length spring plunger in assemblies where a repeatable spring force is needed to hold or locate a component. The 1/4-20 thread makes it compatible with standard tapped holes in metal or plastic workpieces. The 1 inch body length suits shallow-to-medium depth installations. No locking element is incorporated, making it straightforward to install and remove during maintenance cycles. This plunger is commonly used in automated fixtures, machine tooling, and general mechanical assemblies.

Key Features

• 1/4-20 thread with 1 inch thread length for standard tapped hole installation
• 3/16 inch plunger projection with 0.118 inch maximum plunger diameter
• 3 pound initial end force and 13 pound final end force for consistent spring-loaded positioning
• Stainless steel body for corrosion resistance in harsh or wet environments
• No locking element for easy installation and removal
• Hex drive size of 0.0781 inches for precise torque application with appropriate tooling

Compatibility

Designed as a standard 1/4-20 threaded spring plunger suitable for use in any tapped hole application requiring a 1 inch thread length and a 3/16 inch projection spring plunger in industrial, fixture, or mechanical assembly settings.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 1/4-20 hole using the appropriate hex key for the 0.0781 inch hex drive. Ensure the mating hole is clean and free of debris before installation. Do not overtighten, as excessive torque can damage the plunger body or distort the spring mechanism. Always de-energize or lock out any machinery before servicing assemblies that incorporate spring plungers.
