on following page.
The threads of a Regular Flange Hex Locknut have been scientifically
deflected at two 180° opposing sides. The locking concept provides
gripping surfaces on the flank, root, and crest of mating part threads
and a spring-back effect of a body deflection through repeated
shock loads. Reuseable many times. In addition, the nut locks
adequately even when the bolt threads only reach the top of the nut.
