All Metal Self Locking Flange Nut

SKU: SL02 Categories: ,

Self Locking Flange Nut

This is a one piece all-metal self locking nut that also has a captive disc spring washer. The locking feature is achieved by the two de-pitched self-locking slots found on the turret portion of the nut.
When installed on the application the slotted turret section reverts to its original form and each slot grips the shank / thread of the bolt on two different planes and opposite sides.

The self locking feature of this flange nut has many advantages ensuring that the bolt is not damaged, it has high resistance to vibration and is a reusable product. It also has a high resistance to temperature and can be used in volatile environments with temperatures ranging from -200oC to +400oC.

All metal self locking flange nuts are stocked in Metric, UNC & UNF threads.

  • Metric nuts are available in stainless steel A2-70 & A4-80 and in steel grades 8 & 10.
  • UNC & UNF all metal self locking flange nuts are avaiable in stainless steel AISI 304 & AISI 316 and steel grades 5, 8 & 10.
