ITEM NAME:   NUT,PLAIN,ROUND
DEFINITION:  A nut, circular in shape, which may have wrenching facilities such as
             flats, holes, protrusions, slots or splines in or on the periphery or
            in the face opposite the bearing surface. For items having a thickness
             (or height) exceeding two times the outside diameter, use POST,
