The ARP chromoly bolt is a chromoly-threaded fastener sized 7/16-20 x 5.500 that gives a specific length option for secure assembly. It features a 1/2-inch, 12-point head with a black oxide finish for a subdued appearance. Intended for mechanical fastening and fabrication tasks, the 12-point configuration helps when a compact socket engagement is preferred and aesthetics call for a dark finish.
