Hook Bolts

SKU: UB18 Category:

Hook bolts are used in the roofing industry for fixing cladding and roofing panels to steel frames.

Hook bolts are generally supplied with a zinc and yellow plated finish to provide a protective layer to the fixing which gives a good level of corrosion prevention. Further protection is obtained by adding a passivate which results in a yellow (or gold) finish.

These bolts are ideal for roofing as the hook side is not required to be accessed when the fastener is being tightened.

A weatherproof seal can be created when certain washers are used alongside these hook bolts.

Available in a number of lengths, with non-standard sizes available to order.
