40 mm is the go-to length for many natural slate installations because it balances penetration, head coverage and withdrawal resistance. Always follow the project fixing schedule and exposure zone requirements.
| Size | Approx. nails/kg* | Typical use |
|---|---|---|
| 40 mm × 3.35 mm | ≈ 360–420 | Most natural slate roofs; centre-nailed |
*Counts vary slightly by manufacturer, wire tolerance and head type.
For timber-to-lead fixings, choose copper ARS nails (commonly 25 mm × 3.35 mm) for higher withdrawal resistance and thermal-movement tolerance. Stainless is an alternative; avoid plain steel.
