Vlier DBL60N Threaded Ball Plunger 1/2-13 Steel Nylon Ball

Product Description

The VLIER DBL60N is a threaded ball plunger designed for positive positioning, indexing, and light-duty detent applications in mechanical assemblies. It features a 1/2-13 thread size, a 0.281-inch nylon ball, and a zinc-plated steel body measuring 0.75 inches in body length. The nylon ball delivers a maximum reach of 0.072 inches, with an initial end force of 3 pounds and a final end force of 6 pounds. A locking element is incorporated into the design to secure the plunger in position after installation. This part is typically installed by machine builders, maintenance technicians, and tool-and-die professionals working with jigs, fixtures, and precision mechanical components.

The DBL60N is suited for use in light industrial and precision mechanical applications where repeatable positioning or controlled detent action is required. Typical install scenarios include fixture plates, tooling jigs, sliding assemblies, and panel components where a spring-loaded ball provides tactile or functional indexing. The nylon ball construction makes it appropriate for applications where marring of mating surfaces must be avoided. Its standard 1/2-13 thread allows installation into tapped holes in steel, aluminum, or similar structural materials.

Key Features

• 1/2-13 thread size for installation into standard tapped holes
• Nylon ball construction resists marring on mating surfaces
• Steel body with zinc-plated finish for corrosion resistance
• Locking element holds plunger position after adjustment
• 3-pound initial end force and 6-pound final end force for controlled detent action
• Maximum ball reach of 0.072 inches for precise engagement depth

Compatibility

Designed as an OEM-style replacement or new-installation threaded ball plunger for mechanical assemblies requiring a 1/2-13 threaded plunger with a nylon ball and locking element.

Installation Notes

Installation is performed by threading the DBL60N into a pre-tapped 1/2-13 hole using an appropriate wrench or hex key, depending on the drive style of the plunger body. Ensure the mating assembly is de-energized or de-pressurized before installation in any powered or pressurized fixture. Do not overtighten, as excessive torque can damage the locking element or distort the plunger body. Consult applicable machinery safety standards when integrating into automated or high-cycle equipment.
