SureFast product selector

The SureFast fasteners have been designed to fix to various different substrates. For each different substrate, the penetration or embedment of the fastener to the deck will vary, so we have created a selector chart to assist with choosing the correct fastener. The table below provides the standard embedment and penetration for the fasteners, and the image shows how we calculate the build up of the tube washer/fastener combinations.

SureFast Selector Chart

The SureFast selector chart below is designed to assist in the correct selection of fastener and tube combination for fastening flat roofing systems. Simply find the insulation thickness you are fixing through in the first column, and this will give you the correct tube washer length and drive bar length. Then select the correct fastener type and length from columns 4 - 9, depending on the type of deck you are fixing into.

If you have any questions then please call us on +44 (0)1732 882387 and we'll be happy to help.
