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

Product Description

The GIBRALTAR SSW10-4A-G is a threaded spring plunger designed for use in mechanical assemblies where controlled, spring-loaded positioning or detent action is required. The body and nose are both constructed from stainless steel, making this plunger suitable for applications demanding corrosion resistance. It features a 1/4-20 thread with a 1 inch thread length and a maximum plunger diameter of 0.118 inches. The spring delivers 1 pound of initial end force and 4 pounds of final end force, providing consistent engagement across its 3/16 inch projection. This type of component is typically installed by machinists, mechanical assemblers, and maintenance technicians working on fixtures, tooling, and industrial equipment.

The SSW10-4A-G is suited for use in precision fixtures, jigs, machine tool setups, and general industrial assemblies where a compact, threaded positioning plunger is needed. Its stainless steel construction makes it appropriate for environments exposed to moisture, mild chemicals, or frequent cleaning cycles. The standard plunger length type and 1/4-20 thread size make it a common fit for a wide range of manufactured components and aftermarket tooling applications.

Compatibility

Designed as a standard threaded spring plunger for use in mechanical fixtures, jigs, and industrial assemblies requiring a 1/4-20 thread size and stainless steel construction.

Installation Notes

Installation is performed by threading the plunger into a tapped hole sized for 1/4-20 threads using an appropriate hex key or wrench sized to the 0.0781 inch hex drive. Ensure the mating assembly is de-energized or secured before installation to prevent unintended movement. Do not overtighten, as excessive torque can damage the plunger body or distort the spring mechanism. Follow applicable machinery safety and lockout/tagout procedures when installing in powered equipment.
