Gibraltar 67090G Threaded Spring Plunger M6 X 1 Steel

Product Description

The GIBRALTAR 67090G is a threaded spring plunger designed to provide controlled, repeatable positioning and indexing force in mechanical assemblies. The plunger body is machined from steel with a black finish and features a Delrin nose for low-friction contact against mating surfaces. The M6 x 1 external thread allows direct installation into a tapped hole, and the 3 mm hex drive simplifies installation and torque adjustment. With a 1 pound initial end force and a 3.97 pound final end force, this plunger is suited for light-duty detent and positioning applications where consistent spring resistance is required. The 5 mm projection and 3.02 mm maximum plunger diameter keep the overall profile compact.

This spring plunger is used in jigs, fixtures, machine tool slides, assembly tooling, and general industrial equipment where a part must be held in position or indexed reliably under low-to-moderate load. It is typically installed by machinists, tool-and-die makers, and maintenance technicians working on production fixtures or precision mechanical assemblies. The steel body construction makes it appropriate for environments where durability and dimensional stability are priorities over corrosion resistance.

Key Features

• M6 x 1 thread with 25 mm thread length for secure installation in standard tapped holes
• 1 pound initial end force and 3.97 pound final end force for light-duty detent and indexing applications
• Delrin nose minimizes friction and wear on contact surfaces
• Steel body with black finish for durability in industrial environments
• 3 mm hex drive for straightforward installation and adjustment
• No locking element, allowing repositioning as needed

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard M6 x 1 tapped hole applications in jigs, fixtures, and mechanical assemblies requiring spring-loaded detent or positioning plungers.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped M6 x 1 hole using a 3 mm hex key. Ensure the mating hole is clean and free of debris before installation. De-energize or lock out any powered equipment before servicing assemblies containing this plunger. Do not exceed the rated end force range, as overtightening can compress the internal spring beyond its design limits.
