Helical nails from Ancon are quick and reliable fixings for use in warm roof applications. Unlike traditional nails, they rotate as they are driven in, inducing a self-tapping action and consequently do not split timbers or compress the layer of insulation.

Super-8 headed helical nails are designed to secure plywood/insulation composite roof decks to timber joists.

They are manufactured in three standard lengths which suit panel depths from 70mm to 156mm.

Super-8s should be installed at a rate of 8.6 per square metre, using a hammer.
