They come with their own hardened and ground nuts and washers. ARP manufactures them from 8740 chrome-moly steel heat-treated to 190,000 psi, with the threads rolled after heat treatment.\u003c\/p\u003e\u003cp\u003eUse ARP assembly lubricant and their torque specifications, because with a different lubricant the load received by each part will not be the same.
