New from Ancon Building Products, the Staifix Super-8 is a headed helical nail for fixing flat, warm roofs. It is hammered through plywood/insulation composite panels and embeds into the timber joist below to provide a fast, secure fixing.
The Super-8 is manufactured in three standard lengths (135, 165, 195mm) to suit panel depths from 70 to 156mm, and is available in bags of 25 or boxes of 500.
Unlike traditional nails, helical nails rotate as they are driven in, inducing a self-tapping action and consequently do not split timbers or compress the layer of insulation.
Ancon also supplies a wide range of standard cavity wall ties and the Staifix Super-7 which is a stainless steel helical nail for use with pitched, warm roofs.
