Copper Slate Nails 50mm x 3.35mm

These 50mm x 3.35mm copper slate nails are designed for fixing thicker natural slates and diminishing course slate roofs, where increased nail length and secure penetration are required. Manufactured from solid copper, they offer excellent corrosion resistance and long-term durability in exposed external roofing environments.

The extended 50mm length ensures adequate penetration through thicker slate sections and into the timber batten, making them particularly suitable for traditional and heritage slate roofs where slate thickness varies across the roof covering. The 3.35mm shank provides reliable holding strength while reducing the risk of batten splitting.

Copper slate nails are non-reactive and compatible with natural slate, preventing staining, electrolytic reaction and premature fixing failure. They are widely specified for high-quality slate roofing, conservation work and specialist diminishing course installations where best-practice fixing is essential.
