Gibraltar MSDKN50-PT-G Knob Handle Plunger M12x1.75

Product Description

The GIBRALTAR MSDKN50-PT-G is a non-locking knob handle plunger designed for use in indexing, positioning, and clamping applications across industrial and mechanical assemblies. It features an M12x1.75 threaded body with a 25mm thread length and a stainless steel construction throughout. The Delrin knob provides a firm, ergonomic grip for manual adjustment without tools. With an initial end force of 0.56 pounds and a final end force of 1.8 pounds, this plunger delivers consistent, repeatable spring tension. The maximum plunger diameter measures 0.314 inches, and the body length is 1.2 inches. A locking element is included for secure positioning once the plunger is set.

This plunger is suited for light-duty mechanical assemblies where manual indexing or panel positioning is required. It installs into threaded bores on fixtures, jigs, enclosures, and machine frames in manufacturing and fabrication environments. The non-locking plunger design allows for quick, repeated engagement and release, making it a practical choice for applications that demand frequent adjustment. Machinists, maintenance technicians, and industrial assembly professionals are the typical installers for this type of component.

Compatibility

Designed as an OEM-style replacement or direct-fit component for standard M12x1.75 threaded indexing plunger applications in industrial fixtures, jigs, and mechanical assemblies.

Installation Notes

Installation is performed by threading the plunger body into a prepared M12x1.75 tapped bore by hand or with a wrench applied to the 0.472-inch hex. Ensure the mating bore thread is clean and free of debris before installation. Power down or de-energize any associated equipment before servicing components on live assemblies. Do not over-torque the body, as this can damage the threaded bore or the plunger housing.
