Vlier MPRT10 Knob Handle Spring Plunger M10x1.5

Product Description

The VLIER MPRT10 is a non-locking knob handle spring plunger designed for precise, repeatable positioning in mechanical assemblies and fixtures. The plunger features an M10x1.5 thread with a 20mm thread length and a Delrin knob head for smooth manual actuation. Initial end force is 0.22 pounds, building to a final end force of 2.02 pounds, making it well suited for light-duty indexing and locating applications. The maximum plunger diameter is 0.236 inches, and total plunger length is 1.5 inches. This type of component is typically installed by machinists, toolmakers, and maintenance technicians working with jigs, fixtures, and precision equipment.

The MPRT10 is suited for use in industrial machinery, tooling fixtures, and positioning assemblies where a manual, non-locking detent mechanism is needed. Its compact body length of 0.98 inches and length under head of 0.79 inches allow installation in tight panel or housing configurations. The Delrin knob provides a comfortable grip for frequent hand adjustment without tools. This plunger is appropriate for light-load applications in both production and maintenance environments.

Installation Notes

Installation is performed by threading the MPRT10 into a tapped M10x1.5 hole by hand or with a wrench applied to the hex feature. Ensure the mating threaded bore is clean and free of debris before installation. No power source or lockout procedure is required, but confirm the assembly is stationary and not under load during installation. Do not exceed the rated end force by stacking additional spring load without verifying the housing and mating components are rated accordingly.
