WASHERS
Similar to a USS washer, but with slightly smaller inside and outside dimensions, often used in
automotive applications.
A thin, flat circular part with a centrally located hole, designed for assembly around a bolt or
screw, between the bearing surface of the fastener and the part to which it is attached.  Flat
washers are used to improve stress distribution, and to span large clearance holes
