High-Quality Galvanized Clout Nails – Large Flat Head Roofing Nails for Felt & Slate

Our Clout Nails, also known as roofing nails or felt nails, are specifically designed with an extra-large flat head to provide a massive clamping area. This feature ensures that thin materials—such as roofing felt, slate, and sheet metal—are held securely without tearing or pulling through. Manufactured from premium steel and featuring a sharp diamond point, our clout nails offer effortless penetration into timber. Available in Hot-Dipped Galvanized finishes to provide a 20+ year lifespan against rust, making them the industry standard for outdoor construction, roofing, and fencing projects worldwide.

In roofing and exterior construction, the surface area of a fastener is critical. Our Clout Nails are engineered with an extra-large flat head to distribute load effectively, preventing materials like roofing felt and thin sheet metal from tearing. As a specialist roofing nails manufacturer, we produce these fasteners using high-tensile steel to ensure they drive straight and stay secure for decades.

Why Choose Our Large Flat Head Clout Nails?
  • Maximum Clamping Area: The head diameter is typically 3 times the size of the shank, providing superior “hold-down” power for flexible materials.
  • 20+ Year Rust Resistance: Our Hot-Dipped Galvanized (HDG) clout nails feature a zinc coating of ≥50g/m², ideal for harsh coastal or high-moisture environments.
  • Optional Ring Shank: For permanent fixings, we offer ring shank clout nails which provide 50-70% higher withdrawal resistance than smooth shanks.
  • Precision Manufacturing: With a ±0.05mm tolerance on shank diameter, these nails are compatible with both manual hammers and specialized roofing tools.

Frequently Asked Questions (FAQ)

Q1: When should I use Copper Clout Nails instead of Steel?
A: Copper clout nails are essential for natural slate roofing as they are 100% corrosion-proof and will not react with the minerals in the stone, unlike standard steel.

Q2: What is the difference between clout nails and felt nails?
A: They are essentially the same. “Felt nails” is a common term used in the UK for shorter clout nails (usually 13mm-20mm) used for roofing felt.

Q3: How many clout nails are in a 25kg carton?
A: For a standard 30mm x 3.0mm nail, there are approximately 400-450 pieces per kg, totaling over 10,000 nails per carton.
