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

Product Description

The GIBRALTAR MKNL-0-PT-G is a knob handle plunger designed for precision positioning and indexing applications in industrial and mechanical assemblies. It features an M5x0.8 threaded body with a 0.394-inch thread length and a knurled knob head for manual actuation without tools. The non-locking plunger delivers an initial end force of 0.5 pounds and a final end force of 3 pounds, providing consistent, repeatable spring-loaded resistance. With a maximum plunger diameter of 0.0984 inches and a plunger projection of 0.078 inches, this component is suited for light-duty detent, alignment, and panel-mount positioning tasks. A locking element is included in the design.

This plunger is used in machine tool fixtures, jigs, enclosures, and control panels where repeatable hand-operated positioning is required. It threads into a tapped M5x0.8 hole and is actuated manually by the knurled knob head. Typical applications include alignment detents on sliding assemblies, panel latches, and lightweight indexing mechanisms. Machinists, mechanical assemblers, and field technicians install this type of component during equipment assembly or scheduled maintenance.

Key Features

• Non-locking plunger type with spring-loaded end force range of 0.5 to 3 pounds
• Knurled knob head allows tool-free manual actuation
• M5x0.8 thread for installation into standard metric tapped holes
• Locking element included in body design for secure thread retention
• Compact body length of 0.470 inches suits space-constrained assemblies
• Plunger diameter tolerance of +0.000 / -0.001 inch for consistent fitment

Compatibility

Designed as a direct-fit replacement or original-install knob handle plunger for machinery, fixtures, jigs, and enclosures with standard M5x0.8 tapped mounting holes.

Installation Notes

Installation is performed by threading the body into a pre-tapped M5x0.8 hole using the knurled knob head; no special tools are required for standard installations. Ensure the mating tapped hole is clean and free of debris before installation to avoid thread damage. De-energize or lock out any powered equipment before servicing assemblies that contain this plunger. Do not exceed the rated final end force by applying additional external load to the plunger tip.
