Corefix 100mm Heavy Duty Dot & Dab Wall Fixings - Plasterboard Over Blockwork Wall Plugs & Screws - For TVs, Radiators, Shelving & more - Holds 100kg on 4 fixtures - Reinforced Steel Core – Box of 24

If you’ve ever struggled with securing heavy items to drylined walls, Corefix is an absolute game-changer! Unlike standard wall fixings that risk crushing the plasterboard, Corefix secures directly into the solid wall behind, giving incredible strength and stability. I used these to mount a large wall cabinet and a heavy radiator, and they performed flawlessly. The installation is quick and straightforward—just a drill, hammer, and screwdriver are all you need. The engineered steel core ensures the weight is transferred away from the plasterboard, providing complete peace of mind. What really impressed me was the load capacity—tested up to 250kg on four fixings, these are rock solid. Whether you’re mounting TVs, boilers, cabinets, or sanitary ware, it delivers unmatched reliability better than others fixings I have used If you’re a DIYer, plumber, or installer, I’d highly recommend keeping a pack of these on hand. They save time, eliminate the need for extra support, and provide a truly secure fixing. An essential product for anyone working with dot and dab walls!

Used them to mount a heavy shelf. Our house is old and the plaster is basically dust at this point so we needed something heavy duty. These longer plugs get right into the brick and secured the shelf perfectly. Really easy to use. Great idea with the metal inserts ensures the screw doesn’t deviate. Screws seem to be tough and great quality. Highly recommended

Really impressed with these. Easy to use, good quality, very strong fixings.

Excellent fittings, only just found these, absolutely a must for fixing through a dot and dab wall, would highly recommend

Great job

Nice sturdy plugs, drill sizes marked on the box and were accurate. installed very easily. Obvious how to install metal inseret but the video link inc,luded on the box will resolve any doubts. My only slight issue was that there is a thin lip that sits on the wall surface. I can see this is necessary but it could be an issue for some purposes. I used these to hang a radiator on a wall that had been dot and dab finished with insulated platerboard and the end result is very solid.

These are simply well worth the price! After our house underwent a full restoration, and not particularly clued up with what the builder was describing, and finding out what 'dot and dab' plasterboard actually means in real life: these screws are a god send to help overcome problematic issues caused by said new walls! The idea and design behind these screws is a simply one! These screws are long (and strong) enough that they pass through the gap caused by the likes of dot and dab walls, as they end up inside the solid brick part of the wall that then helps create a solid connecting, as it did in our case. Very simple, as once hole has been drilled, then wall plug is inserted, followed by the the screw: and you are left with such a solid finish, that it would probably take the average adults body weight, simply excellent! We only needed to use 3 when mounting a new shelf for a 38 inch TV, again, the shelve was solid, 3 screws possibly a tad overkill? Although, better safe than sorry. Now, going forward, these simply are the only way, as they simplify what became such an irritating job, as having to fill gaps left by the failed wall plugs & screws, just wish we knew about these particular screws before the job was started. Yes, simply a fantastic and sensible product that negates many a issue caused by the likes of dot and dab walls. Recommend very highly.

These are the best plasterboard to wall fixings.

These are great fasteners. Worked excellent for my TV mount.
