Vlier BB58 Ball Button Detent 3/8-16 Thread Stainless Steel

Product Description

The VLIER BB58 is a ball button detent designed for use with spring plunger assemblies in precision positioning and locking applications. Machined from 440C stainless steel, this detent button features a 3/8-16 thread, a 0.3284 inch outside diameter, and a 0.164 inch inside diameter. Overall length is 3/8 inch. The BB58 threads into a mating spring plunger body to create a controlled detent action, holding components in position under repeated engagement cycles. It is installed by maintenance technicians and machine builders working on jigs, fixtures, tooling, and mechanical assemblies.

This ball button detent is suited for light industrial and precision mechanical applications where a replaceable, corrosion-resistant detent contact point is required. The 440C stainless steel construction makes it appropriate for environments where moisture, cleaning agents, or mild corrosives are present. It is compatible with a range of VLIER spring plunger bodies and is sold individually.
