Gibraltar MSW10-10FSL-PTG Threaded Spring Plunger M16 X 2

Product Description

The GIBRALTAR MSW10-10FSL-PTG is a threaded spring plunger designed for precision indexing, positioning, and light-duty locking applications in mechanical assemblies. The plunger features an M16 x 2 thread with a 28.5 mm thread length, a short plunger configuration with a maximum plunger diameter of 7.87 mm, and a projection of 8 mm. Both the body and nose are constructed from steel for durability in industrial service environments. A built-in locking element prevents the plunger from backing out under vibration once installed, making it well suited for machine tool, fixture, and jig applications.

This spring plunger is used wherever a retractable, spring-loaded ball or pin is needed to hold a component in a detent position or provide repeatable part location. The M16 x 2 thread size fits standard metric threaded holes in steel plates, aluminum fixture bodies, and similar industrial components. It is appropriate for light to moderate force indexing tasks. Initial end force is 0.91 kg and final end force is 4.76 kg, giving technicians and machinists a predictable force range for detent and positioning work. Installation is performed by machine assemblers, toolmakers, or maintenance mechanics working on fixtures, jigs, automation equipment, or precision mechanical assemblies.

Key Features

• M16 x 2 thread size with 28.5 mm thread length for reliable engagement in standard metric threaded holes
• Short plunger style with 8 mm projection for compact installation clearances
• Steel body and steel nose construction for strength and wear resistance
• Integrated locking element prevents rotation and back-out under vibration
• Initial end force of 0.91 kg and final end force of 4.76 kg for consistent detent performance
• Maximum plunger diameter of 7.87 mm suits standard metric bore detent geometry

Compatibility

Designed as a direct-fit replacement or new-installation spring plunger for standard M16 x 2 metric threaded holes in industrial fixture plates, jig bodies, machine tool components, and similar mechanical assemblies requiring spring-loaded indexing or positioning.

Installation Notes

Installation is typically performed by a toolmaker, machinist, or maintenance mechanic using a standard hex wrench or spanner suitable for the M16 body. Ensure the threaded hole is clean and free of debris before installation. The locking element should be engaged to the specified torque per the assembler's fixture design requirements — do not overtighten, as this may damage the locking feature or the plunger body. Verify plunger projection and spring force are appropriate for the detent geometry before final assembly.
