Gibraltar IPG-115-G Indexing Plunger M12x1.5 Non-locking

Product Description

The GIBRALTAR IPG-115-G is a non-locking indexing plunger with a knob handle, designed for positioning, locating, and retention applications in industrial machinery and fixtures. Built to Style B configuration, it features an M12x1.5 threaded shank with a 17mm thread length and a 6mm plunger diameter. The steel construction provides durability in demanding shop environments. A lock nut is included for secure mounting. This plunger delivers an initial end force of 6 newtons and a final end force of 14 newtons, making it suitable for light-duty indexing and positioning tasks. Machinists, toolmakers, and maintenance technicians are the primary installers.

This indexing plunger is used in jigs, fixtures, machine tools, and automation equipment where repeatable positioning is required. The knob handle allows for hand-operated engagement and release without additional tools. The non-locking plunger style means the plunger retracts freely under load, which is appropriate for applications where quick repositioning is needed. The included lock nut allows the plunger body to be secured firmly in a threaded bore on a machine frame or fixture plate.

Compatibility

Designed as an OEM-style or replacement indexing plunger for industrial jigs, fixtures, and machine tool applications requiring an M12x1.5 threaded non-locking plunger with a knob handle.

Installation Notes

Installation is performed by threading the plunger body into a prepared M12x1.5 tapped hole in the fixture or machine frame. The lock nut should be tightened against the mounting surface to prevent rotation during operation. Power down or de-energize any associated machinery before installing or servicing indexing hardware. No special tools beyond a standard open-end wrench sized for 14mm across flats are required for the lock nut.
