ARP thermostat housing bolts are available in black oxide-coated chrome-moly steel or ARP’s own “Stainless 300” 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.
