Why 3.35 mm matters for copper slate nails
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.
Sizes, uses and approximate nails per kg
| 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.
Copper nails for leadwork
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.
Quick estimating: how many nails do I need?
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.
