Also more the resistance will also make more resistible in tightening as well as loosening.
Square nut is typically used along with square headed bolt and flat washers.
Square shape made it possible to form a tool in order to tighten a nut. Other reason is wrenching degree . Square nut wrenching degree is 90 and for hex nut it is 60. So hex nut overcomes.
