ARP 670-1004 is a five-piece set of 12-point head bolts machined from ARP 8740 chromoly steel with a black oxide finish. The bolts have an M6 x 1.00 thread and a 35mm under-head length. The 12-point head accepts higher installation torque and fits tight-clearance areas where a standard hex head will not.
