Gibraltar SWPN-3AP-G Threaded Spring Plunger 10-32

Product Description

The GIBRALTAR SWPN-3AP-G is a standard threaded spring plunger designed for indexing, positioning, and light-duty locating applications in industrial assemblies and fixtures. The plunger features a steel body with a phenolic nose and a built-in locking element that secures the plunger in position once installed. The 10-32 threaded body measures 3/4 inches in length, and the plunger projects 1/8 inch beyond the nose face. Initial end force is 1.3 pounds, with a final end force of 2.7 pounds. This part is installed by machinists, tool-and-die technicians, and maintenance professionals working with jigs, fixtures, and precision assemblies.

The SWPN-3AP-G suits applications where repeatable, spring-loaded positioning is required in tight-tolerance bores or threaded mounting holes. Typical use cases include fixture plates, tooling boards, assembly jigs, and light mechanical assemblies where the plunger nose must engage a detent or locating hole. The phenolic nose reduces marking or galling on soft mating surfaces. The locking element holds the installed position under vibration or repeated cycling.

Key Features

• 10-32 threaded body for installation into standard tapped holes
• Steel body construction for durability in industrial environments
• Phenolic nose minimizes surface marking on soft or finished mating parts
• Locking element retains plunger position after installation
• 1.3 pounds initial end force and 2.7 pounds final end force for controlled indexing
• Standard plunger length type with 3/4 inch thread and body length

Compatibility

Designed as an OEM-style replacement or direct-fit component for fixtures, jigs, and mechanical assemblies requiring a 10-32 threaded spring plunger with a standard 3/4 inch body length.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 10-32 hole using a hex key or appropriate driver on the body flats. Ensure the mating hole is clean and free of debris before installation. The locking element should be engaged to the specified torque range for your fixture design — do not overtighten, as this can damage the locking element or thread. Confirm plunger projection and end force are appropriate for the detent geometry before final assembly.
