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

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

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 usedIf 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!

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.

I bought these because we live in the new build with dot and dab walls. I hung some curtain rails and a new shower on our walls and in no time they were coming loose so I replaced all the screws with these and everything is completely solid now. Quite expensive, but well worth it to stop your curtain reels falling off the wall every time your wife tries to tie your curtains and knot when she’s hoovering. Very easy to use drill the hall using the drillbit indicated on the box inside the plug insert the metal support and pop the screwing nice and neat on the wall looks good.

Easy to use, just the job for plasterboard over blockwork. Very pleased. Also, brilliant delivery, ordered late afternoon arrived about 9am next morning.

Remarkable...Excellent product. Simple to use. No hassle . Did the job.

Perfect dot and dab fixing. Used these to secure kitchen units to a dot and dab wall without issue.They do require an M10 hole for the plug and insert but once in the fixing is firm. The insert takes up the gap between the plasterboard and brick/ blockwork. Therfore when tightening you're not going to damage the plasterboard with the insert taking the load and tightening force.Great speciality fixing.

Invaluable for thermolite/aircrete blocks. Recently used to mount 2x sets of shelves, both of which are subject to heavy loads. Allows the weight to be distributed across the various substrates, including front-edge plaster, plasterboard and thermolite behind it. The shelves have been heavily loaded for a number of months now and no hint of any sag - and having drilled and fitted 36 bolts on the first set of shelves, and 54 bolts on the second set, there's also no cracking of adjacent plaster. Win-win.
