The Unifix Galvanised Extra Large Head Clout Nails (20 x 3.00mm) are essential hardware for DIY enthusiasts and trade professionals requiring high-strength fastening for roofing, fencing, and light exterior construction. These nails provide superior grip and long-term durability thanks to their extra-large head profile and corrosion-resistant galvanised coating, though they are specifically sized for thinner materials where a 20mm shank length is appropriate.

While the galvanised finish provides protection against general weathering, they are not specifically rated for extreme salt-air conditions; stainless steel is recommended for those environments.
Yes, their extra-large head makes them a great choice for securing roofing felt or shingles, provided the 20mm length is sufficient for your specific substrate.
No, they are designed to be driven easily using a standard manual hammer.
The shank diameter of these nails is 3.00mm.
The galvanised finish is specifically designed to resist rust when exposed to moisture, making them suitable for most standard exterior DIY projects.
The material may be too soft or the force applied was too great. Consider using a washer or ensuring the nail is not driven beyond the surface of the material.
Ensure you are using a hammer of appropriate weight and striking the nail head squarely. For dense wood, drill a small pilot hole first.
To ensure optimal performance, use a standard claw hammer of an appropriate weight. If driving the nails into particularly dense hardwood, it is recommended to drill a small pilot hole to prevent splitting the timber. While the galvanised finish is weather-resistant, avoid using these nails in direct contact with chemically treated timbers that contain high concentrations of copper, as this may accelerate corrosion. Store the nails in a dry environment to maintain the integrity of the galvanised coating until you are ready to use them.
