- Easy mounting. Lock washer and nut form one unit
- Single piece. Ordering and storage are rationalised
- 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
