Clutch mounting bolts from ARP made from heat treated 8740 chrome moly steel with a black oxide finish. They are nominally rated at 180,000 psi tensile strength providing a substantial extra margin of safety over Grade 8 bolts. Offered in underhead lengths of 30mm to 65mm in 5mm increments.
To retain the bolt we would advise using Schnorr saftey washers and thread locking compound.
