If he uses them on a plasterboard faced wall, the only thing that is going to happen is that he tightens the nut and crushes the plasterboard, unless he applies something in between the nut and the plasterboard that would be large enough to spread the load over a bigger surface area. You do realise that heavy duty fixings for concrete or stone tend to involve a nut on a thread, which needs to be tightened to a specific torque to engage the fixing (thing of the wedge at the end being engaged by tightening the nut against the wall). He could always used some of Scot Titt's glue-ins, of course. I've used them on a breezeblock wall in my garage. ![]() And as I advised early on in the post and others have similarly advised, he needs to get heavy duty fixings for breezeblock. > He's already told you that the plasterboard isn't fixed to battens - it's fixed to glue dabs. (Ps, the first number is the length of the screw, the second being the diameter). Depending on how far off the wall the plasterboard is you may even need a 4" screw(sounds ott i know, but it will fix through all the plugs you've put in the hole). In the past I've used up to half a dozen plugs in one hole just to get a decent fixing. If you drill deeper than is necessary then if the first plug starts to pull out when you tighten the screw then just loosen the screw as if taking it out of the plug that is in the wall, then tap the existing plug back in, you can then put another plug in the hole and try again(effectively you're fixing to 2 plugs as opposed to 1 plug(which is the idea of drilling a deeper hole in the first place), again if this doesn't hold then repeat with another plug and repeat as is necessary, they will eventually hold. Use a brown rawlplug for this size screw. So you would once have asked for 3 1/2" 10's, now though the equivalent is 80mmx5mm. The size of screws, unless you go to an old fashioned type place(ie not screw-up) have all gone metric. You need to screw in tightly, so that the plugs expand and grip, but not so tightly that you pull the shelf brackets through the plasterboard.ĭon't forget to check for electric cables and pipes, etc, etc. You can even blow/suck the dust out of the holes and then glue the plugs in for good measure. I've used them to hold a load of shelves up in the garage, into breeze block and brick.ĭrill through the plasterboard as neatly as you can and then into the breeze block, making sure the drill doesn't wander and make the holes too big, then knock the plugs in until they are flush with the breeze block, not the plasterboard, then screw into them. Or the Rawlplug Uno red, brown or grey fixings and some suitably long screws. Get some decent masonry bits and a good drill - you'll need 6-8mm, depending on the shelf weight - and some suitable plugs, such as these: ![]() Spring toggles won't do you any good - they'll just pull bigger lumps out of the plasterboard.
