The ARP 1/2-20 x 5.250 chromoly bolt is a 1/2-20 threaded fastener with a 5.250-inch length, 12-point head, and black oxide finish. Intended for fabrication and assembly work needing significant threaded engagement and the 12-point drive, it’s useful where a longer chromoly bolt is required to fasten parts while providing the appearance and drive profile of a black oxide head.
