• National Bolt & Nut's premium line of metric serrated flange nuts meet DIN 6923 dimensions with the addition of serrated teeth under flange. These metric serrated flange nuts possess a serrated flange and an enlarged circular base that distributes pressure evenly over the part being secured. Both of these features provide our metric serrated flange nuts with superior gripping capabilities.
  • Because of the tight grip offered by the hardened locking serrations of our serrated flange nuts, no washer is necessary during application. Nylon inserts and nuts with patches are also available, which help prevent our hex flange nuts from loosening during vibration.
  • Other materials and finishes available. For further information, call or send an information request.
