Gibraltar MSW10-2FSP-G Threaded Spring Plunger M4 X 0.70

Product Description

The GIBRALTAR MSW10-2FSP-G is a short-type threaded spring plunger designed for precise, repeatable positioning and indexing applications in industrial and mechanical assemblies. The steel body houses an internal spring mechanism that drives a 1.78 mm diameter steel nose plunger with a projection of 2.5 mm. Thread size is M4 x 0.70 with a thread length of 13 mm. A locking element is integrated into the body to secure the plunger in its threaded seat and prevent rotation or back-out under vibration. This part is typically installed by machinists, toolmakers, and mechanical assembly technicians.

This spring plunger is suited for use in jigs, fixtures, dies, machine tool components, and automation equipment where controlled detent force is required. The short plunger length makes it appropriate for compact assemblies with limited bore depth. Initial end force is 0.23 kg and final end force is 1.81 kg, providing a defined force range suitable for light indexing and positioning tasks. The all-steel construction supports use in moderate-load industrial environments.

Key Features

• M4 x 0.70 thread size with 13 mm thread length for standard metric tapped holes
• Short plunger type with 1.78 mm diameter steel nose and 2.5 mm projection
• Integrated locking element prevents back-out under vibration
• Initial end force of 0.23 kg and final end force of 1.81 kg for controlled detent action
• Steel body and steel nose for durability in industrial environments

Compatibility

Designed as a direct-fit threaded spring plunger for M4 x 0.70 metric tapped holes in jigs, fixtures, and mechanical assemblies requiring a short-projection detent plunger with locking element.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped M4 x 0.70 hole using the appropriate hex key or spanner tool specified for the body style. Ensure the receiving bore is clean and free of debris before installation. The locking element should be engaged after the plunger is positioned to the desired depth to prevent rotation. Do not over-torque the body, as this may damage the internal spring mechanism or locking element.
