I would (pure amateur opinion) have chosen the same screw as used for decking. It sinks in and becomes hidden and handles the outdoor climate without complaining
Mmmm, that was exactly my thought too. However, decking screws are used in pressure-treated wood and are also not painted, so it's a very aggressive environment for the screw. The panel is not pressure-treated and is painted, so it should be quite overkill with decking screws, that was mostly what I was thinking about, one should be able to get by with much "simpler" and cheaper screws. I imagine there should be a bit of a price difference, and if you're going to set a few thousand screws, you could save some money by using the right stuff.
Have used Grabber's PTS when I put up new molding on the house, absolutely superb screw! You can screw very close to the edges without it cracking. The only downside is that it's as expensive as mercury...
If you're going to screw all the paneling, invest in a good screw, otherwise you might as well nail it.
What goes against decking screws is that the head is large, and it's easy to drive it in too far.
Thanks for the tips. I also found Grabber PTS when I was surfing. Funny though, it's called Panel screw and it says it's suitable for board and outer panel, and yet they have sized it for decking.... See below :eek: My panel is 22mm. Guess I'll go with the one for 28mm then, if the wallet allows
I also considered Heco stainless decking screw, I've used them before and liked them, they grip immediately and have a tip that cuts the fibers so you can screw reasonably close to the end, the risk is the head might crack though, but jula has them at a reasonable price.
It seems like most screws recommended for outer panel have the same corrosion protection as for decking. One would think it's not needed.
Why not nails, well, I was planning to use a nail gun, but it doesn't work well with hidden installation near the tongue, which easily cracks, hard to hit exactly right so the nail ends up hidden and also doesn't crack the tongue. Hand nailing? No thanks, I'd rather screw
I bought a package of Grabber PTS, ridiculously expensive and completely useless. Imagine trying to screw ordinary old-fashioned slotted screws with a screwdriver, that's how poorly the bits fit into the screw, losing grip all the time, and you need a lot of power on the driver just to get the screw in at all. It's only out of sheer stinginess that I compel myself to finish the box. After a short while, I had pain in both my wrist and shoulder. And I've screwed tens of thousands of screws in this old house and garage, mainly Torx, without any problems before.
I've also tested regular PH2 deck screws and Torx deck screws, and clearly, the easiest to screw is the Torx; I can hold the driver with two fingers and the screw goes in nicely. The only disadvantage with these two is that it's slightly easier to crack the wood. But with a little caution, it's not a problem at all.
So I’m sorry to say that the rating on a five-point scale for Grabber PTS is nothing more than a horizontal line. The bits I used were the ones that came with the package, and I also tried one I got from a professional, both were equally bad.
Strangely, the grabber usually holds like a rock when using Grabber's own PH2 (a bit slimmer than the regular one), but not quite as well in a standard PH2. Although it has been a long time since I tried, I mostly use Essve nowadays.

Had it been PH2, it would have been 1000 times better, had it been torx, it would have been 100,000 times better. No, here's some crap called 950-1 that some economist, summer worker, or similar came up with. Completely square bits, with low depth, slightly rounded on top, and slightly conical, all to make it lose grip as easily as possible one might assume.

Which Essve screw would you recommend for hidden fastening of single tongue and groove panels?
I had missed that you were looking for hidden mounting (screw in tongue and groove), then I believe most options use Robertson screws (the square drive), I even wonder if Essve has a suitable product (I know they have, e.g., the floor screw that would do the job, though with a Robertson head, but I don't think it has surface treatment for outdoor use).
For me, Robertson has worked well, I used Essve's floor screw for my very unruly pine floor, and sure, I broke a couple of heads, but overall I was more surprised that I didn't break more given how hard I tried to drive some screws.
Almost makes me want to pick up a pack of PTS and see if I also find Grabber's implementation of Robertson as bad as you describe.
Even though I'm not a pro, I have screwed around 10,000 screws or so, and PTS was really the worst experience I've had. One can really wonder why that is because with how bad it was, Grabber shouldn't be selling many screws at all, and that usually results in quick changes. Maybe it's the bits, but then they shouldn't include that garbage; the screw is only as good as the bits they include, you know. Moreover, I had another bit that was just as bad, but on the other hand, it looked exactly the same.
It would be interesting to know why Grabber categorically avoids Torx, which is, in my opinion, the one that works the best. You may have to hold the screw until it grips, but there's clearly the least strain on the hand, wrist, and shoulder compared to the others I've tested.
I also reject the worthless square screw. Managed with an outer wall before I switched to torx. I'll have to live with having different screw heads because I don't think the bits and screws can unscrew the worthless screws. The included bits couldn't handle the contents of the package before it was stripped. Not even a quality bit lasted very long. I've never had problems with Torx.
Square bits must be the worst invention of all time. Even Allen keys are pretty bad, especially rusted ones on cars.. Tend to become the suboptimal "round".
