The ARP chromoly bolt is a 7/16-20 x 5.000-inch 12-point black oxide fastener suitable for fabrication and mechanical fastening. Chromoly construction combined with a 12-point head allows use with common 12-point sockets for compact wrenching access. The black oxide finish delivers a uniform dark appearance and modest corrosion resistance for exposed hardware.
