The length of the nut is 2.5D where D equals the basic major thread diamter.

The bearing surface of the flange has serrations which displace material on the mating surface when the nut is wrenched into place, forming a connection which resists loosening.
Flange provides a more uniform bearing stress to clamp force ratio than other lock nuts
