Good product hold the felt in place well

Good quality

Not exactly what I wanted. The heads are only slightly larger than an ordinary nail and some of the nails were a lot smaller than the 20mm advertised. Go for the 30mm not the 20mm.

I've been using these Clout Nails for a few weeks to install bird combs under the tiles on my roof. These nails are straightforward to use, as you would expect from any standard nail.The quality of these nails appears to be quite good. They have a sturdy build and did not bend during installation, which is a significant plus. Although they haven't been exposed to the weather for long, the galvanized finish suggests they should hold up well against the elements.While there aren't any standout features, the nails did exactly what I needed them to do. The extra-large head and the galvanized finish are practical touches that add to their reliability. If you need nails for roofing or other DIY projects, these should work well for you.Overall, I recommend these nails for their quality and ease of use. They are a solid choice for anyone looking to complete a roofing project or similar DIY tasks.

totally unsuitable for securing felt to shed roofs as these do not have large enough heads.

Does exactly as it should do
