"Finished hex nuts" or "hex whole nuts" are other terms for hex nuts. The Unified inch coarse series (UNC, Unified National Coarse) or Unified inch fine series (UNF, Unified National Fine) are the standard threads (UNF, Unified National Fine). Bolts or screws should be long enough to reach at least two complete threads beyond the nut face after tightening in order to ensure full thread engagement with the hex nut. To ensure that the nut can be tightened properly, two full threads should be accessible on the head side of the nut.
