For profiled polycarbonate sheets (corrugated, Greca, 5-Rib). Not suitable for Twinwall, Custom Glaze or flat acrylic.

We have two different types available:

One Shot fasteners

The best for timber purlins (not suitable for steel)

The One Shot fasteners are very sharp and the washer starts at the bottom. Therefore they are easier to hold on the sheet when drilling. However, because they are so sharp, and start cutting the hole straight away, they do require more care to ensure they are exactly straight and don’t run off.

Multipurpose fasteners

Suitable for steel or timber purlins and high wind zones

The Multipurpose fasteners have a larger washer that starts at the top. Because the drill point can be used on steel purlins as well, it is a little harder to hold on the sheet as it is not as sharp. However it is a lot more forgiving and doesn’t cut the oversized hole until the end. They can be easier for first time users or DIYers.
