Screw exterior panel instead of nail

Hi

I'm just an amateur, but I'm thinking of replacing the house facade that can't be sensibly renovated and replacing it with Siberian larch from a small sawmill nearby.

And I'm considering also using screws, so that much later I can unscrew them. It requires even better screws in my case than the ones you mention, "noble screws" as the carpenters talk about, to handle the forces that larch can exert in every possible direction.

I've been given tips about special variants from NKT, or checking with Ejot, which have worked well in other projects with larch, and you don't need to think much about with mountain paneling.

But everyone I've talked to about screws, who understands that in x decades I want to be able to unscrew the screw, it's only the above that applies. Deck screws are completely out of the question if it is to remain unprotected.

(I'm also going to use iron vitriol and that doesn’t protect the screw.)

But if it's a warehouse like your case, then you're probably never going to unscrew the panel, and in that case, the long-term durability doesn’t matter?

However, I asked both at a local skilled builders' merchant, and with specialists, and if you bought large quantities, I could quickly get screws at a good price, often a better variant than deck screws, so do look around if you want better quality.

I'm not a screw nerd, though, I think Bauhaus themselves should be able to provide the answer on the size you want.

Soft deck screws don't have much strength, but on the other hand, they never rust. Many treated screws can start to rust at the head after driving. Maybe it's only surface rust, but I don't want it on untreated (or vitriol-treated) panels.
Thanks for the tip, found an NKT variant that might work well:

Hi, yes, I saw that variant at Beijer, and it sounds like it should work.

The screw enthusiast there showed even tougher variants from NKT, "noble screws" as the carpenters said, which could withstand forces and attempts to be bent under heavy loads in all directions without breaking, but also be so protected by a treatment/alloying that it wouldn't even have surface rust. Recommended by them in very special cases, like mine with Siberian larch.

But on the other hand, I've borrowed a picka, and it's quite a bit cheaper with stainless nails...

Nothing compared to nailing by hand if you use one of these..

What kind of template is it?
