Gibraltar SWN10-5FS-G Threaded Spring Plunger 5/16-18 Steel

Product Description

The GIBRALTAR SWN10-5FS-G is a short-style threaded spring plunger designed for positioning, indexing, and locating applications in mechanical assemblies. The plunger features a 5/16-18 thread with a 5/8 inch thread length and a steel body for durability under repeated cycling. The Delrin nose provides a low-friction, non-marring contact point suitable for use against finished or delicate surfaces. With an initial end force of 0.5 pounds and a final end force of 10 pounds, this plunger delivers controlled resistance across its 3/16 inch projection range. No locking element is included, making installation and removal straightforward in standard threaded housings.

This spring plunger is suited for use in fixtures, jigs, tooling plates, and machine components where repeatable part location or light detent action is required. The compact short-length profile fits tight-clearance applications in both production and maintenance environments. The Delrin nose minimizes wear on mating surfaces, making it a practical choice for assemblies where metal-to-metal contact is undesirable. Machinists, toolmakers, and maintenance technicians typically install this type of hardware during fixture builds or equipment refurbishment.

Key Features

• 5/16-18 thread size with 5/8 inch thread length for standard tapped-hole installation
• Short plunger length type fits tight-clearance fixture and tooling applications
• Steel body construction for resistance to wear and deformation under load
• Delrin nose material reduces friction and prevents marring of contact surfaces
• 0.5 pound initial end force and 10 pound final end force for controlled detent resistance
• No locking element for simplified installation and removal

Compatibility

Designed as a direct-install threaded spring plunger for any application with a standard 5/16-18 tapped hole requiring short-projection detent or locating function.

Installation Notes

Install using a hex key or appropriately sized driver in the threaded head slot, torquing into the tapped hole by hand until fully seated. Ensure the mating hole is clean and free of debris before installation to avoid thread damage. No special tools or trade licensing are required, though proper thread engagement depth should be verified to achieve rated end force. Confirm clearance for the 3/16 inch plunger projection before finalizing the assembly design.
