About External Star Washer Fasteners –

A
External Star Washer is similar to the Internal Star Washer except
that it has the pointed edges on the outside of the circle with a hole (usually
in the middle) that is normally used to distribute the load of a threaded
fastener, such as a bolt or nut. Other uses are as a spacer, spring washer,
wear pad, preload indicating device, locking device, and to reduce vibration
(rubber washer). Washers often have an outer diameter (OD) about twice their
inner diameter (ID), but this can vary quite widely. Washers are usually made
of metal or plastic depending on the use.
