Super-7 nails fix counterbattens to rafters and install flush to the timber. 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. The nails can be used in line with NHBC standards.

 

Other lengths are available in increments of 5mm.

Note: Ancon recommends a minimum counter batten thickness of 38mm.
