Vlier SSMD60N Threaded Spring Plunger 1/2-13 Stainless Steel

Product Description

The VLIER SSMD60N is a stubby threaded spring plunger designed for precision positioning, indexing, and light-duty detent applications in mechanical assemblies. The body is machined from stainless steel and accepts a 1/2-13 thread, making it suitable for installation into standard tapped holes. The plunger nose is Delrin, delivering smooth, low-friction contact against mating surfaces. Initial end force is 5 pounds and final end force is 28 pounds, giving the installer a predictable force range for consistent part retention. A locking element is included to secure the plunger body in the threaded bore once positioned, preventing rotation or back-out during operation. Licensed industrial maintenance technicians and precision machine builders are the typical installers.

This spring plunger is suited for use in jigs, fixtures, machine tool slides, automated assembly equipment, and similar industrial applications where repeatable positioning or soft detent action is needed. The stubby body profile fits constrained installation environments where standard-length plungers will not clear adjacent components. The stainless steel body resists corrosion in wash-down or mildly caustic environments. No specific OEM model compatibility is stated for this SKU.

Key Features

• Stainless steel body for corrosion resistance in demanding environments
• Delrin nose material provides smooth, low-friction plunger contact
• 1/2-13 thread size with 0.75 inches thread length for secure installation in standard tapped bores
• Stubby body profile suits tight-clearance installation locations
• Locking element prevents back-out and rotation once the plunger is set
• 5 pounds initial force and 28 pounds final force for predictable detent performance

Compatibility

Designed as an OEM-style replacement or direct-fit component for mechanical assemblies requiring a 1/2-13 threaded spring plunger with a stubby body profile.

Installation Notes

Installation is typically performed by industrial maintenance technicians or machine builders using a hex key or spanner wrench suited to the locking element. De-energize or lock out any machine before installing or servicing spring plungers in moving assemblies. Thread the plunger body into a properly tapped and cleaned bore, then tighten the locking element to secure the body position. Do not over-torque the locking element, as stainless steel fasteners are susceptible to galling if driven without lubrication.
