All dimensions are in millimeters.

  • All metal, one piece construction nuts which derive their prevailing-torque characteristics from controlled distortion of the nut thread and/or body.
  • Metal nuts which derive their prevailing-torque characteristics from addition or fusion of a non-metallic insert, plug or patch in their threads.
  • Top insert, two-piece construction nuts which derive their prevailing-torque characteristics from an insert, usually a full ring of non-metallic material, located and retained in the nut at its top surface.
