It's a nut used in fixuring: a heavy flanged hex nut. (Yours does hava
a flange, doesn't it/) 3/8-16 threaded studs, clamp bars, and
stairstep blocks make up a standard fixturing kit with these nuts, and
the 11/16 wrench. Very useful if one owns, say, a Bridgeport milling
machine.
You'd like to replace the NUT or the WRENCH with the same thing,
rather than make one? It wasn't clear to me which you meant.
