Hi everyone!
I need tips on a store that sells larger screw-in studs. It is a screw with M-thread on one end and wood thread on the other end. I need quite large screws, M12*200 and they need to be galvanized.
So, if anyone knows a good place to shop from, I would greatly appreciate the tips!
Thanks in advance!

Thanks for all the tips!
To be more precise, it's a French balcony in galvanized steel that is to be attached to a timber frame. The wall has, from the outside in: panel 22, nail battens 34, insulation 70, and then timber. That's why I need such long and thick bolts.
The initial plan was to use lag screws for the attachment, but due to an ill-considered (read: utterly idiotic!) placement of the mounting holes in the balcony, it's not possible to use lag screws longer than about 140 mm.
It seems like it'll be as Vojma suggests, that I manufacture the screws myself. It'll be expensive screws......

Alfredo: No unfortunately that won't work, the timber is visible on the inside, so it might look a bit odd : )
I wonder how it would work with a threaded rod + suitable adhesive, like a stone installation but in the timber.
The tricky part is that it's a small balcony, so you don't want to take any chances with the installation.....

Now I'm speculating a bit because I have no idea about the standard/finish/condition of your inside. Possibly you could countersink a T-nut from the inside and plug it with similar material as your timber frame. It could range from completely OK to totally unacceptable depending on how it looks overall and what requirements one has...
Alfredo: Not a bad idea! It's painted timber, quite a "rough" finish so it might work!
Another idea. No one knows if there's anything similar to concrete expanders but for wood. I envision some kind of "lump" that deploys strong barbs when you tighten the threaded rod. However, I have no idea if anything like this exists...
www.bult-fast.se has according to the product PDF m12*200
Corre, I am eternally grateful to you!
What a selection! I'm tempted to order a pallet of "good to have" mixed bolts and screws

I would probably rather use a threaded rod all the way through, much stronger. Use a hole saw on the inside to a suitable depth, break out the "lid" with a screwdriver, drill a hole and insert a threaded rod with a large washer and nut. Then it's just about adjusting the "lid" so it fits and pressing it on with suitable adhesive.
Check with https://www.walraven.com/se/ they have screw bolts up to M12 / 200mm.Tiofingers-Perra said:
