Gibraltar SSWN10-5S-PT-G Threaded Spring Plunger 5/16-18

Product Description

The GIBRALTAR SSWN10-5S-PT-G is a stubby threaded spring plunger designed for precision positioning, indexing, and light-duty locking applications in mechanical assemblies. The body is machined from stainless steel for corrosion resistance, while the nose is nylon to prevent marring on contact surfaces. The plunger threads in at a 5/16-18 thread size with a body and thread length of 0.562 inches, a maximum plunger diameter of 0.135 inches, and a projection of 0.084 inches. A built-in locking element secures the plunger in position after installation, preventing loosening from vibration or repeated cycling.

This spring plunger is suited for use in jigs, fixtures, tooling plates, and production machinery where controlled spring force is needed to locate or retain a moving component. The stubby form factor makes it a practical choice in tight clearance environments. Initial end force is 3.7 pounds and final end force is 15.5 pounds, making it appropriate for light to moderate detent and positioning tasks in both manual and automated assembly setups. Installation is typically performed by machinists, toolmakers, or maintenance technicians.

Key Features

• Stainless steel body provides corrosion resistance in wash-down or humid environments
• Nylon nose protects contact surfaces from scratching or galling
• Built-in locking element prevents backing out due to vibration
• Stubby plunger length type fits constrained-depth installations
• 3.7 pound initial end force and 15.5 pound final end force for reliable detent action
• Standard 5/16-18 thread allows installation with common tapping and hand tools

Compatibility

Designed as a drop-in replacement or new-installation threaded spring plunger for jigs, fixtures, tooling plates, and mechanical assemblies requiring a 5/16-18 threaded plunger with stainless steel body and locking element.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 5/16-18 hole using a hex key or appropriate driver on the locking element. Ensure the mating bore is clean and free of chips before threading in. The locking element should be tightened to secure the plunger at the desired projection depth without over-torquing the stainless steel body. Power down or de-energize any automated fixture or assembly before servicing plungers in production tooling.
