Vlier B60 Threaded Ball Plunger 1/2-13 Steel

Product Description

The VLIER B60 is a threaded ball plunger designed to deliver controlled end force in precision positioning, indexing, and detent applications. The spring-loaded steel ball retracts under load and returns under spring pressure, making this plunger suitable for repetitive location and light retention tasks. With a 0.281-inch ball diameter, an initial end force of 6 pounds, and a final end force of 12 pounds, the B60 provides a predictable and repeatable force curve. The 1/2-13 threaded body installs directly into a tapped hole, keeping the assembly compact. This is one of the smallest and lightest spring-loaded devices in its class, suited for applications where space and weight are constrained.

The B60 is used in industrial, mechanical, and light manufacturing settings where a part, fixture, or panel needs to be held in a defined position without a positive latch. Typical applications include jigs, fixtures, tooling plates, sliding assemblies, and drawer or panel indexing. The controlled end force rating makes it appropriate for applications requiring consistent, repeatable detent force rather than a simple friction hold. Installation requires only a tapped 1/2-13 hole. Machinists, tool and die makers, mechanical assemblers, and maintenance technicians are the primary installers.

Key Features

• 1/2-13 threaded body for direct installation into a standard tapped hole
• 0.281-inch steel ball diameter with a maximum ball reach of 0.072 inches
• 6-pound initial end force and 12-pound final end force for controlled, repeatable detent action
• Steel body and steel ball construction for durability in industrial environments
• No locking element - installs and adjusts with standard tooling
• Compact, lightweight spring-loaded design suited for space-constrained assemblies

Compatibility

Designed for use in any application requiring a 1/2-13 threaded ball plunger with controlled end force, including jigs, fixtures, tooling plates, and sliding panel assemblies.

Installation Notes

Install the B60 into a clean, properly tapped 1/2-13 hole using a hex key or appropriate wrench on the body. Ensure threads are free of debris before installation to avoid cross-threading. No staking or adhesive is required, but thread-locking compound may be applied if vibration is a concern in the application. Disengage any spring load on the assembly before removing or replacing the plunger.
