  • Easy installation. Lock washer and nut form one unit

  • Single piece. Ordering and storage are streamlined

  • Quicker and easier installation, especially for overhead work and in places with difficult access

  • Large contact surfaces, better distribution of tension

  • Better overlap for large through holes and slots

  • Protection of workpiece surface. Prevents paint damage and corrosion

  • Can be used at high temperatures

  • Locking effect even under extreme conditions. Drive tension in the washer is greater than the bolt pretension

  • Shorter tightening distance than for standard nuts, no forcing of threads
