This ARP set covers the 7/16-20 thread and ships two nuts per pack. The nuts are machined from 8740 chromoly steel with a black oxide finish, giving greater clamp load and fatigue resistance than an OE nut. The 12-point head works with a thin-wall socket for tight-access fastening. Kit includes 2 nuts.
