Vlier BB46 Ball Button Detent Stainless Steel

Product Description

The VLIER BB46 is a ball button detent spring plunger body designed for precision retention and positioning applications. This stainless steel component accepts compatible plunger assemblies and provides repeatable detent action in mechanisms requiring controlled resistance and release. At 0.1075 inches outside diameter and 0.125 inches overall length, the BB46 is engineered for compact installations where space is constrained. Thread compatibility covers 4-48 and 5-40 fastener standards, making it suitable for fine-threaded assemblies common in instrumentation, fixture tooling, and light mechanical assemblies. Machinists, toolmakers, and mechanical assembly technicians are the typical installers of this component.

The BB46 is used in applications requiring a small-format detent body, including panel assemblies, jigs and fixtures, tooling plates, and precision mechanical devices. The 0.056 inch inside diameter accommodates the plunger pin of compatible ball plunger assemblies. This part is suited for both OEM manufacturing and MRO replacement use where a corrosion-resistant stainless steel body is specified. Compatible plunger assemblies are listed in the compatibility section below.

Installation Notes

Installation is performed by machinists or mechanical assembly technicians using standard taps and threading tools appropriate for 4-48 or 5-40 thread forms. Ensure the mating bore is clean and free of debris before installing the detent body. De-energize or fully disassemble the host mechanism before service to prevent unintended actuation. Do not overtighten, as this can deform the small-diameter body and affect detent function.
