Durlok® self-locking, anti-vibration bolts are designed with long, ramp shaped, radial teeth blended evenly into a smooth slightly conical outer surface. The plain outer bearing ring prevents excessive penetration into the bearing material. Together, these aspects create only moderate edge pressure just sufficient enough to guarantee self-locking. The Durlok Bolt is suitable for multiple re-use because the serrations do not groove the clamped material and maintain locking ability. Moreover, oil or other lubricants, organic or inorganic coatings, will not adversely affect the locking ability.

  • For use with Durlok® Nut. Durlok® 12.9 Bolts & Nuts are designed for high-performance critical applications, that do not require a washer, to guarantee self-locking.
  • Will not loosen or unscrew even under the most severe transverse jarring and vibration.
  • Reusability is guaranteed with locking ability maintained.
  • Unique head design ensures absence of ‘notch-effect’ after assembly.
