Heat treated

ARP Perma-Loc rocker arm nuts are made not to loosen. Reason being, the adjuster body is heat treated all the way through (not just case-hardened), which eliminates "thread" movement. The threads are machined exactly perpendicular to the bottom of the adjuster, so it seats evenly and applies pressure on a full 360-degree circle. The screw is machined flush on the bottom (not pointed) to have optimum contact on the rocker arm stud.
