This 6-pack of flanged locknuts fits Mack applications, with each nut sized M20 x 2.5, a 30mm across-flats dimension, and a 23mm flange measuring 1.02 in. in length. The integrated flange spreads clamping force across a wider area, helping the nut resist loosening from vibration without a separate washer. It is a replacement sold in sets of six.
