Flange lock nuts need to be fully engaged with the bolt/screw threads for the locking feature to be effective. To ensure full thread engagement, bolts/screws should be long enough to allow at least two full threads to extend beyond the nut face after tightening. Conversely, there should be two full threads exposed on the head side of the nut to make sure the nut can be properly tightened.
