Square machine bolts come in many more sizes than Hex Cap Screws but do not have the washer face under the head. Standard thread length is a minimum of twice the diameter plus 1/4" of an inch (or 1/2" if over 6" long). Sometimes you will see a mention of undersized body which means the threads were rolled up from undersized wire instead of cut into standard wire. These parts are limited in availability from stock.
