Avdel structural lockbolts consist of a separate pin and collar which are mechanically locked during installation. Our fasteners form joints capable of withstanding the toughest applications and environments that traditional rivet and screw joints often cannot provide. They offer exceptional resistance to vibration and material fatigue due to the swaged lock which forms collar material permanently into the circular grooves of the bolt.

Avdel lockbolt systems are designed for high strength assembly. Quick and simple to place, they provide tamper-proof joints and are the ideal solution where spot welding is not practical or not possible. They are widely used in demanding engineering industries such as vehicle body building, railways, construction and containers. Key user benefits include:

  • High speed assembly
  • Excellent vibration resistance
  • High shear and tensile strength
  • Tamper-proof joints
  • Consistent high clamp
  • Quick and simple to install
