Vlier BB56 Ball Button Detent 5/16-18 Thread

Product Description

The VLIER BB56 is a ball button detent designed for precision positioning and locking applications in mechanical assemblies. With a 5/16-18 thread, an outside diameter of 0.2659 inches, and an overall length of 5/16 inches, this compact detent fits tight-tolerance installations where repeatable positioning is critical. The inside diameter measures 0.139 inches. Constructed from 440C stainless steel, it offers strong corrosion resistance and long service life in demanding environments. Mechanical assemblers, maintenance technicians, and tooling specialists typically install this component in fixtures, jigs, and positioning mechanisms.

The BB56 is suited for use in industrial tooling, precision fixtures, and mechanical assemblies where controlled indexing or positive part retention is required. Its compact overall length makes it appropriate for space-constrained mounting locations. It is compatible with a range of VLIER plunger series including spring plungers and related detent hardware, allowing it to serve as a replacement or upgrade component in existing assemblies.

Installation Notes

Installation is performed by qualified mechanical or maintenance technicians familiar with threaded precision hardware.
