Vlier DSSBL60N Threaded Ball Plunger 1/2-13 Locking

Product Description

The VLIER DSSBL60N is a threaded ball plunger designed for indexing, positioning, and light detent applications in industrial and mechanical assemblies. It features a stainless steel body with a nylon ball and an integrated locking element that secures the plunger in place once installed. The 1/2-13 thread size allows direct installation into tapped holes. Initial end force is 3 pounds, with a final end force of 6 pounds, making it suitable for light-load positioning tasks where consistent, repeatable engagement is required. Machinists, toolmakers, and assembly technicians typically specify and install this type of component.

The DSSBL60N is used in fixtures, jigs, machine tools, and mechanical assemblies where a spring-loaded ball detent is needed to hold or index a moving component. The nylon ball reduces the risk of marring or damaging mating surfaces, making it a practical choice for applications involving softer materials or finished parts. The locking element prevents back-out under vibration or repeated cycling, which is a common requirement in production tooling environments.

Key Features

• 1/2-13 thread size for installation into standard tapped holes
• Stainless steel body provides corrosion resistance in demanding environments
• Nylon ball minimizes surface damage on mating components
• Integrated locking element prevents plunger back-out under vibration
• 3 pound initial end force and 6 pound final end force for light-load detent applications
• Zinc-plated finish with purple color code for easy identification

Compatibility

Designed as a standard threaded ball plunger for use in tapped 1/2-13 holes in industrial fixtures, jigs, machine tools, and mechanical positioning assemblies.

Installation Notes

Installation requires a properly tapped 1/2-13 hole in the mating component. Use an appropriate wrench or hex key to torque the plunger body without damaging the ball or locking element. Ensure the assembly is de-energized and any moving components are secured before installing or replacing ball plungers in active fixtures. Follow applicable machine safety and tooling standards for the installation environment.
