| Ancon supplies helical nails for both pitched and flat warm roofs. | ||||||||||||||||||||||
| Helical
Nails Helical nails are a quick and reliable fixing 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 or bounce timbers. |

Super-7 Thor-Helical Nails Super-7 nails fix counterbattens to rafters, without compressing the layer of insulation in-between. They are manufactured from stainless steel and are engineered with the precise Thor-Helical patented helix, and so provide maximum corrosion resistance and excellent holding power. They meet the technical requirements of the NHBC. |
