Help, how do I attach wooden strips to concrete blocks?

[Otto-Von-Stern]

I was thinking of installing wooden strips on Leca blocks to attach panels inside the summer cabin. My plan was to attach some strips on the Leca blocks, which I can then nail the panels to. I was thinking of using sill paper as a spacer and either using Weber Leca Screw 409 125mm or galvanized cut nails 75mm.

Now to my little dilemma. I think the Leca screw is too strong and I'm unsure if they will hold well, considering the screws are so large and not intended to be used for small strips. Also, I find the cut nails ridiculously expensive at around 1000 SEK for a 2kg package and not many nails are needed to set up a few strips.

I've tried some different nails but the grip isn't good and I've also asked if you can buy fewer cut nails, but that wasn't possible. So now I'm wondering if you experienced builders have any tips for a clever solution? Perhaps there's a much better way to solve the problem that I haven't thought of?

Spikplugg for leca is what I usually use.

Thanks for the answer Helios, but studying becomes too troublesome. Does anyone know if there are shorter Leca screws than 110mm?

Weber has 100mm.

Beijer has cut nails in bulk

Anyone who has tested both screws and clip nails? Is one preferable?

I also found these clip nails, slightly longer but much cheaper.

In Gothenburg, they only sold 2kg packages last time I was there.

Nail plugs are hammered in directly into the hole with the plug. Everything can be done in one go with a e.g. multi-construction drill. Then you drill through both the trim and into the Leca and then simply hammer in the nail plug, very quick and easy. They are also available with white painted heads.

Expandable nail then, could it be something? You can drill straight through the rule and then it should just be a matter of hammering in.
