ITEM NAME   SCREW,EXTERNALLY RE
DEFINITION  An externally threaded fastener whose threaded portion is of one
             nominal diameter, and whose unthreaded portion has been machined or
             ground in one or more places or over its entire length to a maximum
             diameter less than the minimum pitch diameter of the thread (excludes
             undercut for thread relief). It is No. 0 (0.060 IN.) (1.5 mm) or
             larger, and is designed to be held or driven with either a wrench or
             inserted driver (excluding internal socket and multiple spline types)
             or both in sizes below No. 10 (0.190 IN.) (5 mm) and larger sizes must
             have a head designed for any type inserted driver (excluding internal
             socket and multiple spline types) but may also be designed for
             external wrenching. A locking feature may be incorporated in the
             design of the head or threads. See also BOLT, EXTERNALLY RELIEVED BODY
             and BOLT, INTERNAL WRENCHING.
