Top Locking Nuts, All ASME Grades of Steel
Automation-Style Lock Nuts, Top Locking Lock Nuts or Stover Lock Nuts are lock nuts with a locking feature deformed into the top of the nut. This deformation crimps the internal thread, increasing its friction against the mating bolt or stud, leading to the locking feature.
