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

Product Description

The GIBRALTAR SWPN-3A-G is a standard threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger features a steel body with a phenolic nose, a 10-32 thread size, and a 3/4-inch thread length. The plunger diameter ranges from 0.090 to 0.092 inches with a 1/8-inch projection. Initial end force is 1.3 pounds and final end force is 2.7 pounds, making it suitable for low-force retention tasks. This part is installed by machinists, maintenance technicians, and assembly professionals working on jigs, fixtures, and general mechanical components.

This spring plunger is suited for use in light industrial and mechanical assembly environments where repeatable positioning or detent action is required. Typical applications include fixture plates, machine tool assemblies, enclosure panels, and hardware mounting applications where a small-diameter threaded plunger with controlled spring force is needed. The phenolic nose reduces wear on mating surfaces and is appropriate where metal-on-metal contact is undesirable.

Key Features

• 10-32 thread size with 3/4-inch thread length for standard tapped hole installation
• Steel body construction for durability in industrial environments
• Phenolic nose material reduces surface wear on mating components
• 1/8-inch plunger projection provides positive detent engagement
• 1.3-pound initial end force and 2.7-pound final end force for light-duty retention
• No locking element — installs and adjusts with standard tools

Compatibility

Designed as a standard OEM-style threaded spring plunger for use in any tapped 10-32 hole requiring light-force indexing or positioning detent action in mechanical assemblies.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 10-32 hole using a hex key or screwdriver appropriate to the drive style. Ensure the mating bore or detent surface is clean and free of debris before installation. No special tools or certifications are required, but proper thread engagement depth should be confirmed to achieve the specified end force values. Avoid overtightening, which can damage the thread or restrict plunger travel.
