  3. The WLL applicable to each configuration is the axial WLL multiplied by the loading factor.
  4. The lifting capacity of the eyebolts shall be determined by a competent person. Lifting capacity may be affected by aspects including: asymmetry, load share and load equialisation.


  • General – Eyebolts and eyenuts shall be inspected prior to use.
  • Cleaning – Eyebolts and eyenuts shall be suitably cleaned prior to inspection. There shall be no debris or contaminants present in the thread or underside of collar.
  • Before use – Prior to each use, eyebolts and eyenuts shall be visually inspected to ensure that the devices are free of any significant damage or wear and the size and rated capacity is clearly identified. If any defects are detected, the eyebolt or eyenut shall immediately be withdrawn from service.
  • Periodic – Eyebolts and eyenuts shall be subject to periodic inspection by a competent person at suitable intervals.
