ARP stainless steel header bolts are 15 percent stronger than Grade 8 steel. These 12-point bolts have a compact head that will allow a socket to fit into those tight, tricky spaces next to the headers. These bolts are both highly corrosion-resistant and heat-resistant. They have a polished finish and come in 12-point and hex-style heads. Washers are included.
