Gibraltar MSKNL-0-PT-G Knob Handle Plunger M5x0.8

Product Description

The GIBRALTAR MSKNL-0-PT-G is a non-locking knob handle plunger designed for precision indexing and positioning applications in industrial and mechanical assemblies. Built from stainless steel, it features an M5x0.8 threaded body with a knurled knob head for tool-free adjustment. The plunger delivers an initial end force of 0.5 pounds and a final end force of 3 pounds, making it suitable for light-duty detent and locating work. With a body length of 0.47 inches and a plunger projection of 0.078 inches, this compact unit installs into threaded fixtures and jigs where repeatable positioning is required. Machinists, toolmakers, and maintenance technicians typically install these components.

This plunger is used in machine tool fixtures, workholding setups, industrial equipment panels, and any threaded assembly requiring a spring-loaded locating or detent function. The M5x0.8 thread size and compact form factor make it a common fit for light mechanical enclosures, instrument panels, and precision jigs in both production and maintenance environments. It is sold individually and is suitable for OEM builds as well as field replacement in existing assemblies.
