Why Choose This Product

The oversized ELH head distributes load across a wider surface area, significantly reducing the risk of felt tearing under wind uplift or movement — a critical advantage over standard round wire nails. The galvanised coating provides medium-duty corrosion protection, making these nails dependable in exposed outdoor conditions. Compliance with BS EN 14592:2008 and Eurocode 5 Service Class 2 gives specifiers and contractors confidence in structural and regulatory suitability. The 1kg trade bag format offers excellent value for both one-off DIY jobs and repeat trade use.
