30mm Copper Slate Nails — BS 5534 Practice (1 kg)
Premium 30 mm x 3.35 mm copper slate/clout nails for natural slate, heritage roofing and coastal locations. Copper offers long-term corrosion resistance and excellent pull-out performance for slating when used at the 3.35 mm gauge recommended in modern fixing practice under BS 5534. Annular ring shank (ARS) options are available where extra withdrawal resistance is required for leadwork details.

Why 3.35 mm matters for slating
For slate roofs, 3.35 mm nails provide the head strength and pull-out resistance expected in current UK fixing practice for slating (BS 5534). Choose length by slate thickness and headlap; 30 mm suits thinner slates and vertical cladding where shorter penetration is specified.

Copper nails for leadwork
For fixing lead sheet and clips to timber, use copper annular ring shank nails (often 25 mm × 3.35 mm) to resist movement from thermal cycling. Stainless is an alternative; avoid plain steel. Always follow lead manufacturer guidance.
Choosing the right length
Rule of thumb: nail length ≈ 3 × slate thickness + 15 mm. Always follow the project fixing schedule and exposure zone requirements.
