We do not recommend that you use hookbolts when fixing box profile steel sheeting, 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.

How are these fixed?
These are fixed in conjunction with either a Spat washer and Top Hat or a Seala washer and DEEP Seala Cap, you need to pre-drill the crown of a sheet and feed the hookbolt through, put the washer on then tighten the included nut onto the washer, then clip the Deep Cap or Top Hat over the top for a watertight seal.
What diameter are these?
These are M8 diameter.
Do I need to buy nuts?
No, the box of hookbolts includes a pack of 100 nuts.
What if I need to fit around a scaffold tube?
