Vlier DB60 Threaded Ball Plunger 1/2-13 Steel Nylon Ball

Product Description

The VLIER DB60 is a threaded ball plunger designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. It features a 1/2-13 threaded body machined from steel with a zinc-plated finish and a nylon ball that provides controlled spring-loaded engagement. The ball diameter measures 0.281 inches with a maximum ball reach of 0.072 inches. Initial end force is 6 pounds and final end force is 12 pounds, making it suitable for applications requiring repeatable, low-force positioning. Licensed technicians and mechanical assemblers install this type of component in fixtures, jigs, slides, and production tooling.

The DB60 is suited for use in industrial machinery, assembly fixtures, and precision positioning applications where a spring-loaded detent is needed to hold a component in a set location without a locking element. Its nylon ball minimizes surface marking on mating parts, which is useful in applications involving softer substrates or finished surfaces. The zinc-plated steel body provides corrosion resistance in light-duty shop and production environments.

Key Features

• 1/2-13 threaded body for standard installation in tapped holes
• Steel body with zinc-plated finish for corrosion resistance
• Nylon ball reduces marking on mating surfaces
• 6 pound initial end force and 12 pound final end force for controlled detent engagement
• 0.281 inch ball diameter with 0.072 inch maximum ball reach
• No locking element - installs and removes without thread-locking compounds

Compatibility

Designed as a standard threaded ball plunger for use in any application requiring a 1/2-13 tapped hole and spring-loaded ball detent engagement.

Installation Notes

Installation requires a tapped 1/2-13 hole in the mating component. Use an appropriate wrench on the hex body to thread the plunger to the desired depth and end-force setting. Ensure the mating bore or detent surface is clean and free of debris before installation. Follow applicable machinery safety lockout procedures before servicing any assembly that incorporates this component.
