Tongue-Tite Screws For 18mm Vertical Larch Cladding?

[charliegolf]

Would this be a good solution for hidden fixing a T&G larch cladding job? Or a nailer and 16 gauge brads? Or something else, lol. Thanks.

I've clad before, with rough sawn larch, a 16 gauge brad wouldn't go through it, but they were thick around 20/25mm also they are galvanised and will rust... you really need stainless steel nails to do the job properly.

You might be able to do it with porta nailer, (T&G flooring) but again the cleats are galvanised... they may rust over time, that said they are more robust than brad nailers.

I used waffle head stainless steel nails and had them visible.

Maybe lost head screws might suit you better, the heads are small and I think you can get stainless too.

I used these for my cedar cladding, after asking similar questions at the time, worked great. Looks the same as the tongue tites tho, so may just be a more expensive version of it

We have used the tongue tite screws on larch cladding with no problem.
Just finished a small job using thermowood used same screws again quick and easy.

Thanks both for the reply. Exedon, I'm planning vertical cladding- would the heads be any more visible that way? And (both) did you pre drill all the holes?

 

[23vc]

I didn’t

 

[Exedon]

Only pre drilled if very close to end.
I've done vertical using Siberian larch done properly can't see fixings.

I think I'll go with them...
