Copper Slate Nails 40mm x 3.35mm

These 40mm x 3.35mm copper slate nails are designed for fixing natural and fibre cement slates in roofing applications where durability, corrosion resistance and material compatibility are critical. Manufactured from solid copper, they are non-reactive and prevent staining or degradation when used in exposed external environments.

The 40mm length provides sufficient penetration into timber battens, while the 3.35mm shank delivers reliable holding strength without splitting the batten. Copper slate nails are widely specified for heritage, conservation and high-quality roofing projects, offering exceptional longevity and performance compared to ferrous alternatives.

Ideal for use on slate roofs, traditional pitched roofs and exposed locations, these nails are suited to both new build and refurbishment works where long service life and best-practice detailing are required.
