Vlier SMPRTL10P Locking Knob Handle Plunger M10x1.5

Product Description

The VLIER SMPRTL10P is a locking knob handle plunger designed for precision positioning and holding applications in industrial and mechanical assemblies. Built from stainless steel, this plunger features an M10x1.5 thread size with a 20mm thread length, allowing secure installation into threaded fixtures and fixtures requiring repeatable indexing. The Delrin knob provides a firm grip during manual engagement and disengagement. Initial end force measures 0.22 pounds and final end force reaches 2.02 pounds, delivering a controlled spring load range suitable for light-duty locking and positioning tasks. Machinists, toolmakers, and mechanical assembly technicians typically install this type of component.

This locking plunger is suited for use in jigs, fixtures, machine enclosures, and tooling assemblies where manual positioning or panel retention is required. The locking element holds the plunger in the retracted position, allowing hands-free operation during part loading or alignment. It is appropriate for both light industrial and precision instrument applications where an M10x1.5 threaded body fits the assembly design.

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies, jigs, and fixtures requiring an M10x1.5 locking knob handle plunger with a 20mm thread length.

Installation Notes

Installation is performed by mechanical technicians or toolmakers using standard hex wrenches sized for the 0.39-inch hex body. Ensure the mating threaded hole is clean and dimensionally correct for M10x1.5 before installation. De-energize or lock out any powered equipment before servicing assemblies that contain this plunger. Do not over-torque the body into the fixture, as this may damage the locking mechanism or thread engagement.
