Corefix 24 x 120mm Heavy Duty Dot & Dab Wall Fixings - Plasterboard Over Blockwork Wall Plugs & Screws - For TV Wall Bracket, Radiators, Shelving & More - Holds 100kg On 4 Fixings

Can't recommend these enough for cavity walls that are backed by solid walls. Strongest fixture I've used for going into brick etc through the plaster. Easy to use, sleek and strong. The perfect product. They are obviously more expensive than rawls etc but they're still good value and you buy nice or you buy twice.

I spent some time shopping around and researching what I could use to hold a heavy shelf up to a plasterboard wall. My wall had 27mm insulated board, dot & dab, then brick. I fitted the plasterboard myself, and had squashed it on the wall quite hard, so little gap. I chose these plugs because I estimated there was at least 35mm from the finished surface to the brick. Even a 70mm plug would not have been anchored enough. I was impressed with the simple idea of inserting a metal core to provide strength, and never doubted that these would work. I had to buy the 120m length screws, as the shelf brackets were 15mm thick. I would say fitting them well, takes some skill and is not for an amateur. I used a small pilot bit to get my holes precise. Then an average 10mm masonry bit, will not be quite long enough to drill the hole, so either a long one, or not fully in the chuck for the last 8mm. I then had to use a long 6mm to make the hole slightly deeper, as the 120mm screws would need to go in further than the back of the plug (bracket 15mm thick). You need to be careful to clean the hole out, I used a screwdriver as if the dust gets packed in the end, the plug wont sit home. You can tell if a plug is not going to sit home, and if you are careful you can pull it out and improve or clean the hole. The screws are good quality. Hammering in the metal insert is very satisfying. I only had 2 issues. One hole must have caught a mortar joint, and was slightly off from the plasterboard hole. These plugs do not bend, so had to ream out the p'board. In tackling this, I broke one of the plugs just using moderate force to push it in. my only criticism of these plugs is that the final part near to the flange of the plug is fairly weak - due to cut outs for barbs. There is probably only 50% plastic remaining after the cut outs. Given that its not easy to get these holes 'just right' it would be nice if this part could be improved to allow a bit more robustness when fitting. I'm sure the damaged ones in other peoples reviews / photo's will have been due to not cleaning out the hole and hammering them until they crush. When fitted properly the flange sits a little proud from the wall, but not really noticeable and gives you something to clamp against. The only other issue is that it is hard to get holes in precise places, with a 10mm drill bit. If you don't have any adjustment on your fixing, then you need to take your time and be very careful. I ended up enlarging some of my bracket holes to compensate for the misalignment being a shelf with 4 brackets, it needed to be perfect. A TV mount wouldn't pose this problem. In hindsight, I should have taken my pilot hole into the brick, but I only went through the p'board. I would use again, without a doubt. Great product.

I found these fixings a few year back when I was researching fixing some wall units to my extension walls which are dot and dab.These fixings do take some beating when it comes to heavy loads and to date, my 3 units which are full of office / computer bits are still hanging on in there.. even with boxes on top of the units.Installation of these fixings are a doddle. The size I was using need a 10mm hole drilled through the plasterboard and into the wall.. I think it was about 100mm deep, and then you push the plug into the wall up to the collar..Ill come back to the collar in a mo. Once thats in, you then insert the metal sleeve which transfers the load into the blockwork. You then use it like a normal wall plug installation.The one thing Im not too keen on is the collar on the plug. It protrudes from the sure by a mm or so, which means whatever you are screwing to the wall will sit off the wall slightly.. probably in most cases not an issue, but I was using these to fit a tall radiator bracket to the wall and it was causing it to wobble.I got around this by slightly counter sinking the plug collar into the wall so it was flush. I dont know if that was meant to be done, but it worked for me.These are awesome fixings for substantial loads.

Do exactly as described

I stumbled accross these courtesy of a Youtube video and it has been a right game changer. They are a really simple but very clever design that takes away any lack of trust I had in existing drywall fixings. You may look at them and feel they are quite expensive compared with other fixings but what you are paying for is a lack of hassle and confidence that your 55" TV isn't going to jump off the wall at any time.I am so glad I discovered these - I acually enjoy attaching items to the wall now.

we had just had the house fitted with 30 mil insulation plasterboard so could no longer just use standard fittings. These work tremendously well and only needed 4 to fit a 50 inch plasma TV to the wall.

I was wanting some decent sized fixings to install some Ikea wall mounted furniture and a TV bracket and after some research I decided to opt for these.I opted for these plugs due to living in a new build with dot and dab plasterboard and wanting to get through into the block work to ensure the items being secured were not going to sag over time or fall off the wall. The Plug is long enabling you to secure into the block work, the metal sleeve insert is perfect for providing the support through the plasterboard and into the block work so it won’t sag. They are easy to put into a correctly sized hole with a hammer and are solid once the screw has been inserted to secure the item.The price is a little on the expensive side but worth every penny to ensure safety.

Really good quality
