Plow Nut
Find the spanner that fits it snugly, then measure the hole. Our nut identification chart lists every metric and imperial nut we stock side by side, sorted by spanner size.
The fastest check is the male thread: the right nut spins onto its bolt by hand with no force. Identify the bolt size and pitch first with our bolt and screw guide, and the nut follows.
