ESN100/130 Series

Single slotted nut - Self-locking effect obtained by axial deformation of the upper part of the thread


  • Vibration resistant - Holds the fastener in place even under extreme vibration
  • Temperature resistance - Operating temperature range between -40°C and 280°C
  • Re-usability - Can be fastened and unfastened a minimum of 5 times without compromising minimum required performance according to ISO2320
  • High technical performance for a relatively low price - Excellent value for money
  • High Fatigue resistance - Nut design permits a less aggressive contact during and after installation reducing stress levels inside the bolt and nut

ESN130 - For increased fatigue and mechanical resistance.
