Vlier BB54 Ball Button Detent 1/4-20 Thread 0.2034 Od

Product Description

The VLIER BB54 is a ball button detent designed for use with compatible plunger-style detent assemblies in precision mechanical and industrial applications. Machined from 440C stainless steel, it delivers corrosion resistance and dimensional consistency under repeated cycling. The BB54 measures 0.25 inches overall length with an outside diameter of 0.2034 inches and an inside diameter of 0.1110 inches, making it a compact, drop-in component for the appropriate plunger housings. Installation requires no special tooling beyond what is standard for small-component assembly work. Mechanical assemblers and maintenance technicians are the typical end users for this type of detent component.

The BB54 ball button detent is suited for light industrial, instrumentation, and mechanical assembly applications where a positive locking or positioning action is required. It is intended for use as a replacement or service component within compatible detent plunger assemblies. The 1/4-20 thread size and 0.2034 inches OD make it a precise fit for the supported plunger series listed by the manufacturer.

Installation Notes

Installation of the BB54 should be performed by a qualified mechanical technician familiar with precision detent assemblies. Ensure the mating plunger housing is fully depressurized and free of debris before inserting the ball button detent. Use appropriate small-component handling tools to avoid dimensional damage to the ball seat or seating surfaces. Verify thread engagement and seating depth match the housing specification before returning the assembly to service.
