Snapper Pins

A "snapper pin" is likely a variation of the term "snapper ring" or "snap ring." A snap ring, also known as a retaining ring, is a type of fastener or retaining device that holds components or assemblies in place on a shaft or in a housing bore. It is typically a circular, open-ended ring that can be snapped into a groove on a shaft or inside a bore. Snap rings come in various designs, including internal (for use inside a bore) and external (for use on a shaft). They are used in a variety of applications, such as securing bearings, gears, or other components within a mechanical system. If "snapper pin" refers to a similar concept, it likely denotes a pin or fastener with a snapping or retaining mechanism, possibly used for securing or holding components together in a mechanical assembly. The specific design and use may vary based on the context in which the term is used.
