Galvanised Extra Large Head Clout Nails 20 x 3.00mm 1kg (GEC20B)
This product is a type of Extra Large Head (ELH) Clout Nail, typically made from Carbon Steel and covered with a Galvanised (zinc) coating. The size specifications are 20mm in length and 3.00mm in shank diameter, supplied in a 1kg pack. These nails are specifically designed with a large, flat head to increase the surface area that presses against the material. This feature is crucial for fastening soft or flexible roofing materials like felt, membranes, and sometimes plasterboard, as it provides extra clamping and prevents the material from tearing or pulling over the nail head.
