What is a "clout nail"?

A clout nail is a small, flat-headed nail typically used for fastening lightweight materials like roofing felt, insulation, or thin metal sheets. It has a smooth, round head that helps prevent damage to the material being attached. Clout nails are often used in roofing and construction projects where a secure hold is needed, but a more delicate touch is required to avoid leaving noticeable marks or holes. These nails are available in various lengths to suit different materials and applications.
