Vlier M60N Threaded Spring Plunger 1/2-13 Steel Locking

Product Description

The VLIER M60N is a stubby threaded spring plunger designed for high end-force applications where installation space is restricted. Built with a steel body and steel nose, it accepts a 1/2-13 thread and delivers a 5-pound initial end force with a 28-pound final end force. The plunger diameter measures 0.248 inches, and the projection extends 0.151 inches beyond the mounting surface. A built-in locking element secures the plunger body after installation, preventing loosening under vibration or repeated cycling. Machinists, toolmakers, and mechanical assembly technicians install this type of component in fixtures, jigs, dies, and precision positioning assemblies.

The M60N is suited for applications where a compact footprint is required alongside reliable spring force. The stubby body length of 0.75 inches makes it practical for installations with minimal axial clearance. Typical use cases include workholding fixtures, assembly tooling, index mechanisms, and any application requiring controlled detent or retention force in a confined space. The 1/2-13 thread allows for direct installation into tapped holes in steel, aluminum, or cast iron tooling plates.

Key Features

• Stubby plunger design for restricted-space applications
• 1/2-13 thread with 0.75-inch thread length for secure engagement
• 5-pound initial end force and 28-pound final end force
• Maximum plunger diameter of 0.248 inches
• 0.151-inch plunger projection for controlled detent travel
• Locking element prevents body rotation after installation
• All-steel construction for durability in industrial environments

Compatibility

Designed as a direct-fit threaded spring plunger for tapped 1/2-13 holes in tooling plates, fixtures, jigs, and mechanical assemblies requiring high end force in restricted space.

Installation Notes

Installation is performed using standard hand tools appropriate for 1/2-13 threaded components. Engage the locking element after the body is threaded to the desired depth to prevent rotation during service. Always de-energize or fully unload any associated machinery or tooling before servicing spring plungers in active fixtures. Verify that the mating tapped hole depth accommodates the full thread length to ensure proper seating and force delivery.
