193. In the illustration shown, what is the proper description of the hole represented by «C»
The hole marked 'C' is counter bored; it features a straight-sided, flat-bottom cylindrical enlargement above a through-hole, designed to recess a bolt or screw head. This distinguishes it from a countersunk hole (conical enlargement), a counterdrilled hole (rough enlargement), or a spot-faced recess (shallow counterbore).
