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
             undercuts for thread relief). It is No. 10 (0.190 IN.) (5 mm) or
             larger in size and has a head which is not designed to be held or
             driven with an inserted driver or designed for rotation by the thumb
