Gibraltar SSW10-5-PT-G Threaded Spring Plunger 5/16-18

Product Description

The GIBRALTAR SSW10-5-PT-G is a threaded spring plunger designed for indexing, positioning, and light-duty latching applications in mechanical assemblies. It features a 5/16-18 thread size with a 1 inch thread length and a stainless steel body for corrosion resistance. The plunger delivers a 3 lb initial end force and a 15 lb final end force, making it suitable for consistent, repeatable positioning under moderate spring load. A built-in locking element secures the plunger in position after installation. Machinists, tool-and-die technicians, and mechanical assembly professionals typically install this component in fixtures, jigs, and production machinery.

This spring plunger is used in industrial and manufacturing environments where controlled plunger projection and reliable spring force are required. It fits standard 5/16-18 threaded holes in metal fixtures, machine frames, and fabricated assemblies. The 3/16 inch plunger projection and 0.134 inch plunger diameter suit precision positioning tasks where minimal protrusion is needed. Both OEM assembly applications and field maintenance scenarios are common use cases for this part.

Key Features

• 5/16-18 thread size with 1 inch thread length for standard tapped-hole installation
• Stainless steel body provides corrosion resistance in washdown or high-humidity environments
• Steel nose material handles repeated contact wear in indexing applications
• Locking element secures plunger depth after adjustment, preventing unintended back-out
• 3 lb initial end force and 15 lb final end force for controlled spring-loaded positioning
• 3/16 inch plunger projection (0.134 inch maximum plunger diameter) for precision fitment

Compatibility

Designed as a standard threaded spring plunger for use in any application with a 5/16-18 tapped hole requiring spring-loaded indexing or positioning functionality.

Installation Notes

Installation requires a properly tapped 5/16-18 threaded hole in the receiving component. Disengage or de-energize any associated machinery before installation or removal. Use the hex drive feature (0.094 inch hex size) with the appropriate hex key to thread the plunger in and torque to the required depth. Engage the locking element fully to prevent the plunger from backing out under vibration or repeated cycling.
