BS 5534-conscious 3.35mm gauge copper slate nails in 25–50mm lengths for slate roofing and leadwork. Order online with UK delivery for roofing repairs, re-roofing and heritage work.
Premium copper slate nails for professional slating, heritage roofing and compatible leadwork detailing. This range is based around the industry-standard 3.35 mm gauge commonly associated with BS 5534 best practice for slate fixing. Choose annular ring shank (ARS) options for leadwork where increased withdrawal resistance is required.
For slate roofing, 3.35 mm gauge copper nails are widely used because they help provide the pull-out resistance, head strength and durability expected in modern fixing specifications under BS 5534:2014+A2:2018. Slates are commonly fixed with two nails per slate unless the project specification states otherwise. Always choose nail length to suit slate thickness, headlap and required batten penetration.
| Size (Gauge) | Typical Use | Approx. nails/kg* |
|---|---|---|
| 25 mm × 3.35 mm (ARS) | Lead clips, flashings, soakers and general leadwork | ≈ 450–500 |
| 30 mm × 3.35 mm | Thinner slates or vertical slate cladding | ≈ 430–470 |
| 40 mm × 3.35 mm | Many natural slate roofs | ≈ 360–420 |
| 50 mm × 3.35 mm | Thicker slates or more exposed locations | ≈ 300–360 |
*Approximate counts for guidance only. Counts vary by manufacturer, head type and production tolerance.
For fixing lead sheet and lead clips to timber, copper annular ring shank (ARS) nails are often used for improved withdrawal resistance and material compatibility. A common option is 25 mm × 3.35 mm, but always follow the lead manufacturer’s guidance and project-specific fixing detail.
Slate roofs are commonly fixed with two nails per slate unless the specification says otherwise. Your total quantity depends on slate size, gauge, headlap and site exposure. As a practical allowance, include extra for cuts, eaves, verges and detailing. If you are unsure, send us your slate size and headlap and we will help you estimate.
Yes. This range is based around the 3.35 mm gauge commonly used for slate fixing in line with BS 5534 best practice. Always follow the slate manufacturer’s guidance and your project fixing specification.
A useful rule of thumb is: nail length ≈ 3 × slate thickness + 15 mm. 40 mm suits many natural slates, while 50 mm is often chosen for thicker slates or more exposed locations.
For lead sheet and clips fixed to timber, copper ARS nails are commonly specified where increased withdrawal resistance is required. Follow the lead detailing guidance for your system.
Approximately 300–500 nails depending on size. See the table above for typical counts.
Yes — see stainless steel slate nails, aluminium slate nails, and sheradised clout nails.
Copper slate nails used for slating should align with BS 5534 best-practice fixing principles. The commonly specified gauge is 3.35 mm.
Copper nails are widely used in slate roofing because of their durability, corrosion resistance and compatibility with natural materials such as slate and lead. This range supports the practical intent of BS 5534:2014+A2:2018 for slate fixing when specified and installed correctly.

Copper nails are widely used for slate roofing, heritage repairs and leadwork because they resist corrosion and are compatible with traditional roofing materials.
Yes. This range uses the 3.35 mm gauge commonly associated with slate fixing best practice in line with BS 5534. Always follow the slate manufacturer’s guidance and your project specification.
A useful guide is: nail length ≈ 3 × slate thickness + 15 mm. 40 mm suits many natural slates, while 50 mm is often used for thicker slates or more exposed conditions.
As a guide: 25 mm ≈ 450–500, 30 mm ≈ 430–470, 40 mm ≈ 360–420, 50 mm ≈ 300–360 nails per 1 kg bag. Counts vary by manufacturer and head type.
Copper is a traditional choice for slate and heritage work. A4 stainless steel may be preferred in particularly aggressive coastal or industrial environments. Use whichever the project specification requires.
