PRW Main Cap Side Bolts uses premium grade Custom 4135 Steel rated at "aircraft" quality. Their side bolts are then specially heat-treated to 180,000 psi. This heat-treating procedure allows for total heat penetration which results in a stronger, more superior stud compared to lesser quality studs from other manufacturers. PRW main cap side bolts are then centerless ground after being heat treated and then thread rolled which assures better fatigue strength than having this process done before heat treatment. This manufacturing process may cost more to do but the results are well worth the extra effort.
