Pocster Posted May 2, 2019 Share Posted May 2, 2019 Hey all ! Right i’ve Got some of this metal stud work to install in my dungeon . Is it best ( does it matter ? ) to fix to ceiling and slab that I drill and use screw and rawplug or drill and just use concrete screws ?? cheers Link to comment Share on other sites More sharing options...
Pocster Posted May 2, 2019 Author Share Posted May 2, 2019 (edited) Actually thinking about it raw plugs might be better as shorter . Ceiling is 100mm thick . I’ll wait for @Onoff to tell me what to do ... ? Edited May 2, 2019 by pocster Link to comment Share on other sites More sharing options...
makie Posted May 2, 2019 Share Posted May 2, 2019 Could use hammer-fixing or anchor bolts Link to comment Share on other sites More sharing options...

AdamSee Posted May 2, 2019 Share Posted May 2, 2019 (edited) I guess it depends what your hanging from the ceiling. Is it a light weight item or is it going to be in the 75 - 150kg range? Edited May 2, 2019 by AdamSee Link to comment Share on other sites More sharing options...

Construction Channel Posted May 2, 2019 Share Posted May 2, 2019 What exactly is the ceiling build up? Surely it can't be just a 100mm concrete slab? Link to comment Share on other sites More sharing options...

Are you no longer having the roof as a drive-on area? Also, are you planning on doing a plasterboard ceiling under the concrete? Link to comment Share on other sites More sharing options...

Lol Yes , you can still drive on it - so that area would be polythene block paving I’m planning to have a suspended ceiling somehow ... Link to comment Share on other sites More sharing options...
Construction Channel Posted May 2, 2019 Share Posted May 2, 2019 Sounds mighty complicated. Ct1 it up. Maybe a couple of screws to hold it in place. Personally I don't like perforating structural concrete things like lintols with screws. Afaic it's just asking for trouble 1 Link to comment Share on other sites More sharing options...

Roundtuit Posted May 2, 2019 Share Posted May 2, 2019 Just tried concrete screws into block work for fixing battens but didn't get on with them (kept stripping the pilot hole out), so went back to screws and plugs. Maybe what you need are 'concrete ceiling anchors': https://www.screwfix.com/p/fruilsider-suspended-ceiling-anchor-one-size-60-x-6-x-6mm-100-pack/8349t 1 Link to comment Share on other sites More sharing options...
Onoff Posted May 2, 2019 Share Posted May 2, 2019 Don't ask me, I've gone right off concrete screws recently! Well, as of last night! Got quite a few of these 7mm Easy Drive ones left over from studding the walls out. Even back then I had the odd one not take. Thought I'd give them another go battening out the bathroom cupboard. Drilled the requisite 6mm hole. Not a chance were they going in! Makita impact gun just said no! Couldn't be ar5ed going to 6.5mm. Brown plugs and 6x90 Forge Fast screws for this lot: 1 Link to comment Share on other sites More sharing options...
Mr Punter Posted May 2, 2019 Share Posted May 2, 2019 Hilti gun fastenings are used a fair bit for metal ceiling systems. Link to comment Share on other sites More sharing options...
Construction Channel Posted May 2, 2019 Share Posted May 2, 2019 Concrete screws. 5.5mm in celcon/soft red 6mm in fibolite/ normal brick 6.5mm in concrete/ fletons Don't keep winding them in. Let it bite then stop! 1 Link to comment Share on other sites More sharing options...
