Vlier SLRM12P Locking Knob Handle Plunger M12x1.75

Product Description

The VLIER SLRM12P is a locking knob handle plunger designed for precision positioning and indexing applications in industrial machinery, fixtures, and tooling assemblies. It features an M12x1.75 thread with a 0.65-inch thread length and a countersunk knob style for low-profile installation. The locking element holds the plunger in the retracted position, eliminating unintended engagement during setup or operation. Initial end force is 1 pound, building to a final end force of 10 pounds, providing reliable spring-loaded retention. Installed by maintenance technicians and machine builders working with positioning mechanisms and adjustable assemblies.

The SLRM12P is suited for use in industrial and manufacturing environments where a threaded, spring-loaded plunger with a positive locking feature is required. Typical applications include jig and fixture positioning, machine guarding latches, conveyor alignment stops, and adjustable workholding setups. The countersunk knob design keeps the head close to the mounting surface, making it appropriate for space-constrained installations.

Key Features

• Locking plunger type holds plunger retracted until deliberately released
• M12x1.75 thread for direct installation into tapped holes
• Countersunk knob style for reduced head clearance requirements
• 1 pound initial end force to 10 pounds final end force for controlled spring tension
• Maximum plunger diameter of 0.25 inches with 0.25-inch plunger projection
• Hex size of 6 millimeters for wrench installation and torque control

Compatibility

Designed as a direct-install locking knob handle plunger for any application with a standard M12x1.75 tapped hole requiring spring-loaded plunger retention.

Installation Notes

Installation is typically performed by machine builders, maintenance mechanics, or tooling technicians using a standard 6 millimeter hex wrench. Ensure the receiving bore and tapped hole are free of debris before threading the plunger body into place. De-energize or lock out any machinery before servicing or replacing plunger components per applicable LOTO procedures. Do not exceed the rated end force range by modifying the spring or plunger assembly.
