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 M8 threads (8 x 1.25mm thread pitch) and a 12mm long fully-threaded shank. The 12-point head takes a small 10mm wrench, but provides a full 15mm OD bearing surface. Head measures 7.4mm tall overall.
The ARP 300-Series 12-Point M8x1.25 Nuts (Part No. ARP300-8310, sold separately) are a perfect match for these bolts!
