Tried with Grabbers, worked well.
Gunnebos seems interesting though. Also cheaper! However, it seems to only be available in professional stores.
 
Yes, the price is not entirely unimportant if they function equivalently otherwise.

Gah, was planning to nail the playhouse to avoid expensive Grabber but then realized it's almost impossible to nail in some places. What do you think about decking screws? Can they handle 22x120 boards and the weather changes with shrinking and swelling wood when the length is perfect, or are panel screws more durable?

I have a lot of decking screws at home but not panel screws. Some decking screws have such poor tensile strength that I'm a bit worried they'll snap when the wood moves.

Buy screws for the purpose. It's foolish to skimp, it rarely pays off in the end, unfortunately.

I know, and I'm trying to stop doing that. It turned into an expensive playhouse, but it's self-manufactured. I'll have to go buy windows for 700 and screws for 600 or 900 tomorrow :)

My precious! Will nail most things in the future but as a mechanical engineer it's a bit of porn :)


A pile of steel screws arranged closely, showing their sharp tips and threaded bodies, used for construction and assembly projects. Box of 250 Grabber panel screws, 4.2x48 mm, for outdoor use.

Which screw for panel = nail :)

Well banded in a popgun
This project is just a playhouse, at the cottage I nailed by hand last summer when I renovated the roof and replaced many cover boards. Quite meditative to hammer in 4 and 5” all day but nail guns are probably much faster.

Hammer on a partially shingled playhouse roof, surrounded by wooden beams and trees.

Good coil in the nail gun
I have also come to this conclusion. Screws sounded good and I was considering using a screw gun, but they only seem to go up to 55 mm and that's a bit tight for the siding board. Plus, I think nails look better.

What do you think about mixing?
That is, screw the bottom board quite close to the edge (~15mm) so that the screw head is hidden behind the siding board. One screw per "nail batten" but zigzag on alternating sides. Then nail the siding board with a nail gun. By the way, does anyone have tips on:

1. Good screw gun / good collated panel screws?
2. Good coil nail gun / good collated panel nails?

Nails look better, but if you were to use screws, you should use 75 mm screws for the cladding board or battens. Otherwise, use a 4” nail.
 
I had also thought about this, but then I read somewhere that it's important the nails/screws do not penetrate the underlying wind barrier. In my case, with 28x70 nail battens and 22 mm base/cover boards, that means panel screws/nails of 48 mm and 70 mm. With ring-shanked panel nails, I hope the cover board holds sufficiently anyway... Now I'm mostly wondering where I should buy the following screws and nails cheaply:

1. For the base board:
- Stripped self-drilling panel screws (48 mm, Corrosion Class C4)?
2. For the cover board:
- Stripped panel nails with a round ring-shanked shaft (70 mm, hot-dip galvanized) for a round strip nail gun?

The downside of nails is that it becomes slightly more difficult to move boards when placed a little wrong or slightly crooked. However, much uglier.

Use horizontal planks, then a cover board at each post. It looks nice with screws.

I'll get back to you when I've tried screwing. These Grabber ones have a very discreet head. BUT - I'm a bit skeptical about screwing since it's supposed to be a helluva job to dismantle when that day comes. It's easy with a crowbar to dismantle many, many years later without destroying too much. I doubt you can unscrew most screws after 10-15 years if something needs fixing.

Going to screw paneling (22mm) on a shed
Yep! Worked just as well as Grabbers.
