  • Reduced risk of damage to the surface of components thanks to the large, smooth washer face (also advantageous in reducing the risk of corrosion)
  • The large washer integrated into the screw head reduces any loss in prestressing force.
  • The large, effective rubbing surface under the head increases security against unscrewing (for torque-controlled tightening)


Cost savings:

  • Shorter assembly preparation
  • Faster assembly
