Vlier DSSBH60 Threaded Ball Plunger 1/2-13

Product Description

The VLIER DSSBH60 is a threaded ball plunger with a 1/2-13 thread size, designed for indexing, positioning, and light-duty detent applications in mechanical assemblies. The body is machined from stainless steel and measures 0.75 inches in length. A nylon ball with a 0.281-inch diameter extends a maximum of 0.072 inches at full reach. Initial end force is 6 pounds, with a final end force of 30 pounds. This plunger is installed by maintenance technicians and mechanical assemblers working with fixtures, tooling, slides, and positioning components.

Threaded ball plungers in this size class are commonly used in industrial fixtures, jigs, machine tool components, and assembly line tooling. The 1/2-13 thread allows installation into standard tapped holes in steel, aluminum, or plastic housings. The stainless steel body resists corrosion in light-exposure environments, while the nylon ball provides low-friction contact and protects mating surfaces from scoring or marring. This plunger suits applications where repeatable, spring-loaded detent positioning is required without a locking element.

Key Features

• 1/2-13 thread size for installation in standard tapped holes
• Stainless steel body provides corrosion resistance
• Nylon ball protects mating surfaces and reduces friction
• 6-pound initial end force and 30-pound final end force for reliable detent action
• Maximum ball reach of 0.072 inches for controlled engagement depth
• No locking element - allows straightforward thread-in installation and removal

Compatibility

Designed as an OEM-style threaded ball plunger for use in standard 1/2-13 tapped holes across mechanical assemblies, fixtures, jigs, and positioning tooling.

Installation Notes

Installation requires a standard 1/2-13 tapped hole in the mating component. De-energize and lock out any powered equipment before servicing assemblies containing this plunger. Use appropriate thread engagement depth to avoid bottoming out the body and restricting ball travel. Inspect the seating surface for wear or damage that could affect detent force consistency.
