Specifications

Which one do I need?

Roofing screws are chosen by diameter and length. This 5.5mm size is a slightly slimmer option than the heavier gauges, and the 32mm length suits fixing a sheet down onto its support where the combined thickness is modest. Measure what the screw must pass through and allow enough length to engage properly.

How to use

1. Mark where the support runs under the sheet so each screw hits it.
2. Use a hex socket on your drill driver that matches the head.
3. Hold the screw square and let the self drilling point cut through.
4. Tighten until the rubber washer is snug and sealing, but not squeezed out sideways.
5. Use proper access equipment and never stand directly on fragile sheets.
