ITEM NAME:   SCREW,SHOULDER
DEFINITION:  An externally threaded fastener whose threaded portion is of one
             nominal diameter, No 0 (0.060 IN.) (1.5 mm) or larger. It has a round
             unthreaded neck or shank all or part of which is of greater diameter
             than the threaded portion. The head is designed to be driven with
             either a wrench or an inserted driver or both in sizes below No. 10
             (0.190 IN.) (5 mm) nominal diameter. No. 10 (0.190 IN.) (5 mm) and
             larger sizes must be designed for any type of inserted driver, but may
             also provide for external wrenching of the head. A locking feature may
             be incorporated in the design of the head or threads. For items which
             are both shouldered and have an externally relieved body, use SCREW,
             EXTERNALLY RELIEVED BODY. For items with a No. 10 (0.190 IN.) (5 mm)
             or larger thread diameter without an inserted driver head, use BOLT,
             SHOULDER. Excludes BOLT, INTERNAL WRENCHING and SCREW, CAP, SOCKET
