Easy, fast AAC block fasteners

Postby Sometimewoodworker » Sat Mar 26, 2016 12:16 pm

We have found that when you want to attach pipe clips direct to AAC blocks that there is no need for wall plugs or any kind of drilling. 50mm/2“ plasterboard (or drywall) screws will do the job. You need the coarse threads and the 50mm length, shorter ones can pull out, just drive them straight in.

They are not easy to find but you can get them by mail order from
http://www.thaicarpenter.com then search for Drywall screws

This should work as a direct link

Also when putting upstainless steel netting to prevent beam to wall cracking a wide-crown staple gun with 13mm staples will speed up work a lot

Both of these will speed up getting the job done and will be about 3 to 5 times faster than most other methods.

Interesting Jerome. When you say 'drive them straight in', do you mean with a hammer or a screwdriver?

Well if you use a Birmingham screwdriver :shock: you might snap the screws and they would easily pull back out so I used a regular screwdriver or my Festool drill

I think the term drywall screws here is more akin to American stud wall building and not plasterboard.

I actually know those screws as "bugle headed chipboard screws" they come with every Ikea diy packs if you notice.I actually have a few but damned if I can remember where I found them (no I havent been to Ikea)

As for fixing to AAC block, for something simple like pipe brackets and the e.m.l mesh I have recently found that good old stainless 1 inch masonry nails are perfect (the thick ones from Global). The flat head on the nail pins the mesh down well, and it needs to, because that stuff has a life of it own and very difficult to lay flat.

Just another option if you dont have a stapler.

The term "drywall screws" is the name they go by on the Thaicarpenter website, they are very hard so a little brittle. I suspect the chipboard screws are a bit softer so less likely to snap if over driven. I have no idea if the plasterboard screws are the same or not.

As to the masonry nails a picture would be helpful, I don't remember seeing any stainless nails.

Yes, my mistake they are not stainless but Chromium and very light for concrete and masonry.

^Thais call the hard nails into concrete wall/plaster "concrete", whilst they call concrete structure "cement" or pun in Thai.

:lol: :lol: yes you are right, Thai logic in action.,,,but there are some Westerners here that call concrete "cement," and mortar "cement" also so its not all one sided.
remember folks cements is but one component only!

Given me an idea for an instore grilling about the nails being made of metal not concrete.

i often refer to these nails as "ta poo" but i may have misheard it years ago?

More likely to be zinc than chromium I think, I tried those into our garden wall as well as masonry nails from my nail gun, the wall was mostly the winner.

They are probably OK into cinder block and the longer ones will probably be OK into AAC blocks, but then any nail will go into AAC.

Definitely not chrome, they would be really heavy and super expensive. Maybe 410 stainless, (12% Chrome).
