Brand: Automotive Racing Products (ARP)
These high-strength metric ARP bolts are great for installing most accessories. The 180,000 psi tensile strength bolts are made of 8740 chrome moly with a black oxide finish. All bolts are packaged in sets of 5 bolts with matching washers.
These bolts have a M6 threads (6 x 1.00mm thread pitch) and a 20mm long fully-threaded shank. The hex head takes a small 8mm wrench, but provides a full 11.6mm OD bearing surface. Head measures 6.5mm tall overall.
The ARP 300-Series 12-Point M6x1.0 Nuts (Part No. ARP300-8370, sold separately) are a perfect match for these bolts!
