Vlier DB50AP Threaded Ball Plunger 8-32 Steel Nylon Ball

Product Description

The VLIER DB50AP is a threaded ball plunger designed for precision positioning, detenting, and indexing applications in mechanical assemblies. The plunger features an 8-32 thread size, a steel body with a zinc-plated finish, and a nylon ball measuring 0.094 inches in diameter. The body length is 0.344 inches with a maximum ball reach of 0.025 inches. Initial end force is 0.5 pounds and final end force is 1.25 pounds. A locking element is included. This type of component is installed by machinists, maintenance technicians, and mechanical assemblers working with jigs, fixtures, tooling, and precision equipment.

The DB50AP is suited for light-duty detenting and positioning tasks where a soft ball material is needed to protect mating surfaces. The nylon ball minimizes wear on delicate or coated contact surfaces. The compact 0.344-inch body length makes it appropriate for shallow-thread applications and tight-clearance assemblies. The 8-32 thread allows installation in standard tapped holes found across a wide range of industrial and mechanical components.

Key Features

• 8-32 thread size for compatibility with standard tapped holes
• Nylon ball (0.094 inches diameter) protects mating surfaces from scratching or marring
• Steel body with zinc-plated finish for corrosion resistance
• Locking element included to secure the plunger in position after installation
• Initial end force of 0.5 pounds and final end force of 1.25 pounds for light-duty detenting
• Compact body length of 0.344 inches suits tight-clearance applications

Compatibility

Designed as a standard threaded ball plunger replacement or new installation for mechanical assemblies, fixtures, and tooling that use 8-32 threaded holes requiring light-force detenting with a nylon ball contact.

Installation Notes

Install using a hex key or appropriate driver into a pre-tapped 8-32 hole. Disengage or de-energize any moving or powered components before servicing the assembly. The locking element should be engaged after positioning the plunger to the desired extension depth. Avoid overtightening, as the steel body and locking element can damage threads in softer parent materials if excessive torque is applied.
