Gibraltar IPG-117-G Indexing Plunger M16x1.5 Knob Handle

Product Description

The GIBRALTAR IPG-117-G is a non-locking indexing plunger with a knob handle, designed for positioning and locating applications in industrial machinery, fixtures, and tooling assemblies. Built to Style B configuration, this plunger features an M16x1.5 threaded body with a 23mm thread length and an 8mm diameter plunger with 8mm of projection. The steel construction provides durability under repeated actuation. An integrated lock nut is included for securing the plunger in the mounting location. Initial end force is 15 newtons and final end force is 35 newtons, making it suited for light-duty indexing and detent positioning tasks.

This indexing plunger is used in applications where a spring-loaded retractable pin is needed to register, locate, or lock a rotating or sliding component in position. Typical installations include machine tool fixtures, assembly jigs, rotating tables, and adjustable industrial equipment. The knob handle allows for tool-free manual retraction of the plunger during operation. The M16x1.5 thread fits standard metric tapped holes found in many European-standard and ISO-compliant machine frames and fixtures.

Installation Notes

Installation is performed by threading the plunger body into a pre-tapped M16x1.5 hole and securing with the integrated lock nut. Ensure the mounting surface is clean and the thread engagement depth accommodates the full 23mm thread length. Power down or de-energize any equipment before servicing or replacing indexing hardware. Torque the lock nut to the equipment manufacturer's specified value using an appropriate wrench across the 19mm nut flats.
