ARP 12-Point Black Oxide Bolts - M6 x 1.00 x 12mm - 5 Pack

ARP 670-1016 is a 12-point head bolt in M6 x 1.00 thread with a 12mm fully threaded shank, machined from 8740 chrome moly and rated to 180,000 psi tensile strength. The 12-point head accepts an 8mm wrench and presents an 11.6mm outside diameter bearing surface standing 6.5mm tall, a more compact footprint than a hex head of the same strength, which helps it index in tight castings and against close brackets. The black oxide finish adds corrosion resistance. Each pack holds five bolts with matching washers.
