Vlier BL60 Threaded Ball Plunger 1/2-13 Steel

Product Description

The VLIER BL60 is a threaded ball plunger designed to deliver controlled end force in indexing, positioning, and detent applications. The body is made from steel and houses a 0.281-inch steel ball with a maximum reach of 0.072 inches. Initial end force is 3 pounds, with a final end force of 6 pounds. The 1/2-13 thread and 0.75-inch body length make this one of the smallest and lightest spring-loaded plunger devices available. It is installed by machine builders, toolmakers, and precision assembly technicians where repeatable low-force positioning is required.

The BL60 is suited for use in fixtures, jigs, tooling plates, and light-duty mechanical assemblies where a compact, threaded plunger is needed to hold position or provide tactile feedback under controlled force. The small form factor allows installation in tight spaces where larger plunger styles cannot fit. This part is sold individually with a minimum order quantity of one.

Compatibility

Designed as an OEM-style replacement or direct installation component for applications requiring a 1/2-13 threaded ball plunger with controlled spring force in fixtures, jigs, and precision tooling assemblies.

Installation Notes

Install into a clean, properly tapped 1/2-13 threaded hole using appropriate hand tools. De-energize or lock out any machinery before installing or servicing plunger components in automated equipment. Do not exceed the rated ball reach or apply side-loading forces that could deform the ball seat. Consult applicable machine tool or fixture design standards for torque and engagement requirements.
