Gibraltar MSKNL-1-G Knurled Knob Non-locking Plunger M6

Product Description

The GIBRALTAR MSKNL-1-G is a non-locking spring plunger with a knurled knob handle, designed for indexing, positioning, and light-duty holding applications in industrial and mechanical assemblies. The plunger threads into an M6x1.0 tapped hole with a thread length of 0.512 inches and delivers a spring end force that ranges from 1 pound initial to 4 pounds final. The maximum plunger diameter is 0.118 inches with a plunger projection of 0.118 inches. The body length measures 0.630 inches. Machinists, toolmakers, and assembly technicians install this component in fixtures, jigs, enclosures, and equipment panels where repeatable detent positioning is required.

This spring plunger is suited for light-force detent and positioning work in machine tool fixtures, industrial enclosures, control panels, and assembly jigs. The knurled knob allows hand adjustment without a driver, making it practical for applications requiring frequent repositioning. It is appropriate for both production tooling environments and low-volume custom fabrication setups where a compact M6-threaded spring plunger is needed.

Key Features

• Non-locking plunger design allows free spring-loaded travel without a locking element
• Knurled knob handle enables tool-free hand adjustment in the field
• M6x1.0 thread fits standard metric tapped holes with 0.512 inches of thread engagement
• Spring end force range of 1 pound initial to 4 pounds final suits light indexing and detent applications
• Compact body length of 0.630 inches for use in space-constrained assemblies
• Plunger diameter tolerance of +0.000 / -0.001 inches for consistent fit and function

Compatibility

Designed for installation in any assembly or fixture with a standard M6x1.0 tapped hole requiring a non-locking spring plunger with knurled knob actuation.

Installation Notes

Installation is performed by threading the MSKNL-1-G into a pre-tapped M6x1.0 hole by hand or with light tooling. De-energize or lock out any powered equipment before servicing assemblies containing this component. Ensure the mating hole depth and thread count are sufficient for the full 0.512 inches of thread engagement. Do not overtighten, as the knob handle is intended for hand-force installation and adjustment.
