This is a ten-pack of ARP 12-point nuts in the 7/16-20 thread size. Each nut is machined from 8740 chromoly steel and black oxide finished, giving greater clamp load and fatigue resistance than an OE nut. The 12-point profile pairs with a thin-wall socket for tight-clearance work. Kit includes 10 nuts.
