Vlier DSSBL62N Threaded Ball Plunger 5/8-11

Product Description

The VLIER DSSBL62N is a threaded ball plunger designed for precision indexing, positioning, and detent applications in industrial and mechanical assemblies. The plunger features a stainless steel body with a nylon ball, providing corrosion resistance and low-friction contact suited for light-load positioning tasks. The 5/8-11 thread allows secure installation into standard tapped bores. With an initial end force of 4.5 pounds and a final end force of 9 pounds, along with a locking element, this plunger delivers consistent, repeatable engagement across its 0.096-inch maximum ball reach. Machinists, toolmakers, and maintenance technicians install this type of hardware in fixtures, jigs, and automated equipment.

The DSSBL62N is suited for use in precision fixtures, assembly tooling, machine guarding, and component-positioning systems where a controlled detent force is required. Its nylon ball minimizes surface marring on mating components, making it appropriate for applications involving sensitive or finished surfaces. The locking element feature helps resist loosening under vibration, which is common in production machinery and equipment subject to repeated cycling.

Key Features

• 5/8-11 thread size for installation into standard tapped bores
• Stainless steel body for corrosion resistance in demanding environments
• Nylon ball contact for low-friction, non-marring positioning
• Locking element resists loosening under vibration
• Initial end force of 4.5 pounds with final end force of 9 pounds for consistent detent engagement
• Zinc-plated finish for added surface protection

Compatibility

Designed as a direct-threaded replacement or new-install ball plunger for industrial fixtures, jigs, tooling plates, and mechanical assemblies requiring a 5/8-11 tapped bore.

Installation Notes

Installation is performed by threading the plunger into a pre-tapped 5/8-11 bore using the appropriate wrench on the body hex. Ensure the bore is clean and free of debris before installation to prevent thread damage. Torque to the level specified by the assembly drawing or fixture documentation - do not over-torque, as this can damage the locking element or distort the body. Verify ball travel and detent force function correctly before returning the assembly to service.
