Gibraltar MSW10-5A-PT-G Threaded Spring Plunger M8x1.25

Product Description

The GIBRALTAR MSW10-5A-PT-G is a metric threaded spring plunger designed for indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger features an M8 x 1.25 thread with a 0.866-inch thread length and a standard plunger projection of 0.118 inches. The steel body and steel nose deliver durability in industrial environments. An integrated locking element secures the plunger in position after installation, eliminating the need for separate locking hardware. Initial end force is 2.02 pounds and final end force is 7.87 pounds, making this unit suitable for moderate-resistance positioning tasks on production equipment, fixtures, and assemblies.

This spring plunger is used in tooling fixtures, jigs, machine components, and precision assemblies where repeatable part positioning or detent action is required. It threads directly into a tapped M8 x 1.25 hole and is installed by machinists, tool-and-die makers, and maintenance technicians working on industrial equipment. The locking element feature makes it well suited for applications subject to vibration where a standard non-locking plunger would back out over time.

Key Features

• M8 x 1.25 metric thread for direct installation into standard tapped holes
• 0.866-inch thread length provides full thread engagement in typical fixture stock
• Standard plunger projection of 0.118 inches with a maximum plunger diameter of 0.138 inches
• Steel body and steel nose construction for industrial durability
• Integrated locking element prevents loosening under vibration
• 2.02 lb initial end force and 7.87 lb final end force for moderate-resistance positioning

Compatibility

Designed for installation in any component or fixture with a tapped M8 x 1.25 metric threaded hole requiring a standard spring plunger with locking element.

Installation Notes

Installation is performed with a hex key or appropriate drive tool sized to the plunger body. Ensure the receiving hole is tapped cleanly to M8 x 1.25 before threading in the plunger. De-energize or lock out any machine before servicing fixtures or assemblies containing spring plungers. The locking element should be engaged fully to the specified seating depth to function as designed.
