Vlier SSLFM6P Locking Knob Plunger M6x1.0

Product Description

The VLIER SSLFM6P is a locking knob spring plunger designed for indexing, positioning, and holding applications in light industrial and mechanical assembly work. It features an M6x1.0 threaded body with a 0.4 inch thread length and a knurled locking knob head that allows the plunger to be locked in the retracted position for easy part loading and unloading. The maximum plunger diameter is 0.12 inches with a plunger projection of 0.13 inches. End force ranges from 0.5 pounds initial to 2 pounds final, making it suitable for low-to-moderate holding force requirements. Machinists, toolmakers, and mechanical assemblers install this component in jigs, fixtures, and equipment panels.

The SSLFM6P is commonly installed in machine tool fixtures, assembly jigs, and panel-mounted indexing applications where the operator needs to lock the plunger in a retracted position before engaging the workpiece. The knurled knob provides a secure grip for manual operation without additional tooling. Its compact body length of 10 mm makes it a practical choice for space-constrained assemblies requiring a reliable, repeatable positioning mechanism.

Key Features

• Locking knob holds plunger retracted for hands-free part loading
• Knurled knob style for secure manual grip without tools
• M6x1.0 thread for broad compatibility with standard tapped holes
• Low initial end force of 0.5 pounds rising to 2 pounds final for controlled engagement
• Compact 10 mm body length suits tight-clearance fixture designs
• 0.13 inch plunger projection provides positive, repeatable indexing reference

Compatibility

Designed as a standard-format locking spring plunger for M6x1.0 tapped holes in machine fixtures, assembly tooling, and industrial equipment panels.

Installation Notes

Installation requires a properly tapped M6x1.0 hole to the appropriate depth for the 0.4 inch thread length. Thread the plunger in by hand using the knurled knob, then tighten to the manufacturer-recommended torque using a suitable tool on the head if required. Ensure the plunger axis aligns with the intended detent or index point before final installation. Depressurize or de-energize any associated equipment before servicing fixtures that incorporate this component.
