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

Product Description

The GIBRALTAR SWN10-5FS-PT-G is a threaded spring plunger designed for use in fixtures, jigs, tooling, and mechanical assemblies where controlled, repeatable positioning or retention is required. The steel body provides durability in industrial and trade environments. The nose is made from Delrin, offering a low-friction contact surface that resists marring on finished workpieces. A locking element is included, securing the plunger in the threaded bore once adjusted to the correct position. With a 5/16-18 thread and a 5/8 inch thread length, this is a short-style plunger suited to applications with limited depth clearance.

This plunger is used in workholding fixtures, automation equipment, and mechanical assemblies requiring a spring-loaded locating or positioning component. The short plunger length type makes it well suited to shallow-threaded housings. It provides 0.50 pounds initial end force and 10.00 pounds final end force, making it appropriate for light-duty indexing and positioning tasks. Licensed tradespeople and industrial maintenance professionals working on fixtures, conveyor systems, or precision tooling are the typical installers.

Key Features

• 5/16-18 thread size with 5/8 inch thread length for common metric-free tooling applications
• Steel body construction for strength and longevity in industrial environments
• Delrin nose material provides a low-friction, non-marring contact surface
• Locking element locks the plunger in place once positioned in the threaded bore
• Short plunger length type suited to shallow-depth threaded housings
• 0.50 pounds initial end force and 10.00 pounds final end force for light-duty positioning

Compatibility

Designed as an OEM-style replacement or direct-fit component for threaded spring plunger applications using a 5/16-18 thread standard in mechanical fixtures and industrial assemblies.

Installation Notes

Installation is typically performed by maintenance technicians or tooling specialists using standard hex wrenches or a spanner wrench appropriate to the plunger head style. Always de-energize or lock out any machine before servicing spring plunger components in automated or powered equipment. Thread the plunger into the bore by hand first to avoid cross-threading, then torque to the fixture manufacturer's specification. The locking element should be engaged after final position adjustment to prevent rotation during operation.
