These fasteners deliver superior strength and meet the ARP 'ZERO defect-ZERO failure' quality standard. Hardened and parallel ground washers are included to ensure even load distribution and accurate torque readings.

All Pro Series bolts have a reduced wrenching 12 point head and wide area flange to eliminate the need for valve train removal for cylinder head retorquing .
