Vlier BL60N Threaded Ball Plunger 1/2-13 0.281 in Ball

Product Description

The VLIER BL60N is a threaded ball plunger designed for controlled end-force applications in precision mechanical assemblies. It features a 0.281-inch steel ball, a steel body measuring 0.75 inches in length, and a maximum ball reach of 0.072 inches. The BL60N is engineered as one of the smallest and lightest spring-loaded positioning devices available in this thread class, making it well suited for compact assemblies where space and weight are critical constraints. A built-in locking element secures the plunger in position after installation. Initial end force is 3 pounds and final end force is 6 pounds, providing consistent, repeatable detent action across the service life of the assembly.

This ball plunger is used in indexing, positioning, and detent applications across mechanical, industrial, and light manufacturing environments. The 1/2-13 thread size suits standard tapped holes in metal fixtures, jigs, tooling plates, and machine housings. Its controlled end-force spec makes it appropriate for any application requiring predictable, low-force ball engagement without the bulk of larger spring plunger designs. The purple color code aids in identification during assembly and maintenance.

Key Features

• 1/2-13 threaded body for installation in standard tapped holes
• Steel body and steel ball construction for durability in industrial use
• 0.281-inch ball diameter with 0.072-inch maximum ball reach
• 3-pound initial end force and 6-pound final end force for controlled detent action
• Integrated locking element to retain position after installation
• Compact, lightweight 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 indexing fixtures, tooling plates, and precision mechanical assemblies.

Installation Notes

Installation is performed by threading the BL60N into a properly tapped 1/2-13 hole using an appropriate wrench or driver. Ensure the mating hole is clean and free of debris before installation. Do not over-torque the body, as this can damage the locking element or distort the thread. Confirm ball movement and engagement force after installation before returning the assembly to service.
