For items with a thickness less than those indicated above, see shim. For items with one hole centrally located conforming to the above dimensional criteria use washer, flat or spacer, ring as applicable. When thickness and/or outsidediameter or smallest overall outside dimension is designated as a tolerance /dimension the maximum dimension will be used to determine compliance.
