Gibraltar MSSW10-8-G Threaded Spring Plunger M12 X 1.75

Product Description

The GIBRALTAR MSSW10-8-G is a threaded spring plunger with a stainless steel body and nose, designed to provide controlled positioning, indexing, and holding force in mechanical assemblies. It features an M12 x 1.75 thread with a 1.102-inch thread length and a standard-length plunger projection of 0.157 inches. Initial end force is 10.12 pounds and final end force is 24.73 pounds, making it suitable for applications requiring moderate spring resistance. This plunger is typically installed by machinists, toolmakers, maintenance mechanics, and precision assembly technicians working with jigs, fixtures, and tooling components.

This spring plunger is suited for use in industrial tooling, fixture plates, machine components, and positioning assemblies where repeatable spring-loaded contact or detent action is needed. The stainless steel construction makes it appropriate for environments with moisture exposure or where corrosion resistance is a priority. It installs into any tapped M12 x 1.75 threaded hole, fitting both light-duty and moderate-force holding applications across manufacturing and maintenance settings.

Key Features

• M12 x 1.75 thread with 1.102-inch thread length for secure engagement in standard tapped holes
• Standard plunger projection of 0.157 inches (4.00 mm) for controlled contact depth
• 10.12-pound initial end force and 24.73-pound final end force for moderate holding and indexing performance
• Stainless steel body and nose material for corrosion resistance in demanding environments
• No locking element — allows straightforward installation and removal without thread-locking inserts
• Compact and lightweight at 0.05 pounds for use in space-constrained tooling and fixture designs

Compatibility

Designed for installation into any tapped M12 x 1.75 threaded hole in tooling fixtures, jig plates, machine bases, or mechanical assemblies requiring a standard spring plunger configuration.

Installation Notes

Installation is performed by maintenance mechanics or toolmakers using a hex wrench or spanner appropriate for the plunger body. Ensure the receiving hole is properly tapped to M12 x 1.75 before installation to avoid cross-threading. De-energize or lock out any associated machinery before servicing the fixture or assembly. Do not exceed the rated final end force by over-compressing the plunger, as this can damage the spring mechanism.
