When it comes to securing roofing felt, membranes, or sheet materials outdoors, the last thing you want is a nail that lets you down. Forgefix 3.00 x 20mm Felt Nails are engineered to give you a secure, lasting fix — every single time — so your roofing projects stay watertight and intact for years to come.

Say goodbye to torn felt, pullthrough failures, and premature rust. These nails tackle the most common frustrations of roofing and cladding work headon:

• No more pullthrough or tearing — the oversized nail head spreads the load across a wider surface area, holding flexible or lightweight sheet materials firmly in place without damaging them.
• Built to survive the elements — a hotdipped galvanised (D2) coating provides a robust barrier against rust, moisture, and weathering, keeping your fixings as reliable in five years as they are on day one.
• Perfect penetration depth — the 20mm length drives cleanly into timber substrates, offering a firm grip without splitting or overpenetrating the material beneath.
• Great value, ready to work — supplied in a practical 0.5kg bag, you get a generous quantity to power through sheds, summerhouses, outbuildings, and cladding jobs without running short midproject.
• Trusted by professionals and DIYers alike — whether you're a seasoned roofer or tackling a weekend project, these nails deliver the performance and reliability you need to get the job done right.

Don't let inferior fixings compromise your hard work. Invest in nails that are purposebuilt for outdoor sheet fixing — and enjoy complete confidence in every strike of the hammer.
