We do not recommend that you use hookbolts or scaffold bolts when fixing box profile steel sheet, drillscrews should be used wherever possible to ensure the most watertight and reliable fixing point. If the only option is hookbolts due to the layout of the steel supports then it is recommended that specialist bonded profiled saddle washers are used that sit over the crown of the profile.
