Screws, what brands do you use that last

[Olaf3]

What are your experiences and recommendations regarding outdoor wood screws in construction?

I had to replace a large number of screws in the outdoor stairs because they broke straight off, and I've never experienced anything like that. 6*90 C4 from Biltema hasn't lasted more than a year outdoors. The stairs don't move much in the cold, so I suspect Biltema screws are low quality.

I also had a lot of Biltema deck screws that broke.
I think Heco works well.

I think Gunnebo and Fischer are good. For something important, I use at least A2, and if it will be visible, A4. A4 is the only one that holds up well over time. Heco is ok, but I think Gunnebo is better.

Unprotected structures outdoors can be tricky, especially when sturdier dimensions are involved. A few years ago, I built a deck with 45x195 as the decking. I screwed it with Heco 6x100. Sometimes it sounded like gunshots when these screws snapped, for example in the cold. My own conclusion was that these large planks moved too much between the seasons, and the screws couldn't always handle it.

I use Biltema's wood screws for outdoor use and have never had them break except now when I made a mold. The ones that are c4 are probably made of too hard material, just like the anchor screws they have, they just break. Or I use TFT Jetting Screws.

Above all, it is important that the materials you are screwing together are tightened so that there is no gap. The friction between the materials then holds movements that might shear off the screw.

Overall, I think Essve's range is good.

Building my deck now.
The construction started 2 years ago, so now I'm replacing diagonal braces with a proper railing, and many screws have broken.......
Biltema is a likely supplier, but I don't remember.........
Klantskallejag bought more Biltemaskruv the other day, but in the future, it'll only be Esseve...
