Vlier BH60 Threaded Ball Plunger 1/2-13 Steel

Product Description

The VLIER BH60 is a threaded ball plunger designed for controlled end-force applications in mechanical assemblies. It features a 0.281-inch steel ball with a maximum reach of 0.072 inches and a 3/4-inch steel body threaded to a 1/2-13 specification. The BH60 delivers 6 pounds of initial end force and 30 pounds of final end force, making it suitable for indexing, positioning, and detent functions where consistent spring-loaded engagement is required. As one of the smallest and lightest spring-loaded devices in its class, it is specified by mechanical engineers and installed by machinists, maintenance technicians, and assembly professionals in production and repair environments.

The BH60 is used in light-duty mechanical positioning applications including jigs, fixtures, machine tool components, and automated assembly equipment. Its compact 1/2-13 threaded body allows installation in tight-clearance locations where larger plungers cannot fit. The controlled end-force range from 6 to 30 pounds suits applications requiring repeatable, low-profile ball engagement without a locking element.

Key Features

• 1/2-13 threaded body for direct installation into tapped holes
• 0.281-inch steel ball with 0.072-inch maximum reach
• 6-pound initial end force and 30-pound final end force for controlled detent action
• Steel body and steel ball construction for durability in industrial environments
• No locking element - allows easy torque-in installation and repositioning
• Compact, lightweight form factor suited for space-constrained assemblies

Compatibility

Designed as a direct-install threaded ball plunger for any assembly or fixture with a 1/2-13 tapped hole requiring spring-loaded ball detent or positioning functionality.

Installation Notes

Installation is performed by machinists or maintenance technicians using a standard hex wrench or spanner tool sized for the body. Thread the BH60 into a clean, properly tapped 1/2-13 hole and torque to the assembly specification for the application. Ensure the ball engagement surface is smooth and free of burrs to avoid premature wear on the steel ball. De-energize or lock out any machine before servicing or replacing plungers in active assemblies.
