ARP® uses a premium grade 8740 chromoly that is rated far superior to to "aircraft quality". Then, each bolt is placed vertically in special racks and precisely heat-treated to 200,000 psi. This procedure ensures complete heat penetration and the results are far superior to those lesser quality bolts from other manufacturers who just dump pieces in a basket and hope for the best. Following heat-treat, each bolt is centerless ground to make it as close to perfectly concentric as possible.This procedure involves about ten very slight cuts and results in an exceptionally straight part. It s important to note that lesser quality bolts are not even centerless ground the material is thread rolled in bar stock form (mostly before heat-treat, when the material is easier to machine). Because ARP® bolts are manufactured to such exacting tolerances, you will note that gaskets and cylinder heads literally glide into position and are perfectly aligned something that won t happen with inferior quality head bolts. ARP® bolts are thread rolled after heat-treat, which gives them about 1000% (thats ten times) better fatigue strength than those bolts that are threaded prior to heat-treat (a very common industry practice). It costs a lot more to do it this way, because it s tough on tooling, but the results are well worth the extra effort.
