03Technical description

The UNC flange lock nut in zinc plated carbon steel is a fastener for inch assemblies with vibration where wide bearing and locking against loosening are required. At TECTUL it is specified by material, thread system and actual available size, because in industrial nuts compatibility depends on diameter as well as pitch and bearing type. For this product, the reference works with UNC thread and DIN 6926 functional reference for prevailing-torque flange nuts in equivalent metric families. It differs from the UNF version by its coarse thread and from the conventional lock nut by the integrated flange. It is a useful option for maintenance, manufacturing and replacement purchases when the correct part must be identified without mixing similar catalog families.

  • Use a bolt or stud with material and strength compatible with the nut.
  • Clean the thread and discard parts with dents, burrs or visible deformation.
