Description
ARP cast aluminum valve cover bolts are available in black oxide-coated chromoly steel or ARP’s own âStainless 300â material. The bolts are rated up to 170,000 psi and the stainless versions are impervious to corrosion or extreme heat. The heads on the bolts feature either 12-points or a hex head so they can be tightened easily in small increments. Centerless ground flat washers are included to distribute the tightening load over a wider area.
