Vlier MPRTL10 Locking Knob Handle Plunger M10x1.5

Product Description

The VLIER MPRTL10 is a locking knob handle plunger designed for use in positioning, indexing, and clamping applications where controlled spring force and positive locking are required. Threaded at M10x1.5 with a 20mm thread length, this steel plunger features a Delrin knob for hand operation without tools. Initial end force is 0.22 pounds and final end force is 2.02 pounds, providing a predictable force range suited to light-duty locating and retention tasks. The body measures 0.98 inches in length with a maximum plunger diameter of 0.236 inches and a plunger projection of 0.196 inches. Machinists, toolmakers, and industrial maintenance technicians are the primary installers of this component.

The MPRTL10 is suited for machine tool fixtures, jigs, workholding equipment, and industrial assemblies where a hand-adjustable locking plunger is needed. The M10x1.5 thread fits standard metric threaded holes common in European-spec and metric-standard equipment. The Delrin knob allows manual engagement and locking without a wrench, making it appropriate for frequent operator adjustments on production machinery, enclosures, and positioning fixtures.

Compatibility

Designed as an OEM-style replacement or direct-install component for metric-threaded fixtures, jigs, and industrial assemblies requiring an M10x1.5 locking knob handle plunger.

Installation Notes

Installation is typically performed by machinists or industrial maintenance technicians. Thread the MPRTL10 into a clean, properly tapped M10x1.5 hole and use the hex flats (0.39 inches across) to torque to the assembly specification defined by the equipment manufacturer. De-energize or lock out any machine before servicing plunger components in powered equipment. Do not exceed the rated end force range by modifying the plunger spring or substituting non-OEM components.
