If you’ve ever struggled with securing heavy items to drylined walls, Corefix is an absolute game-changer!

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!

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.

Very good product.Care must be taken when drilling into hard block as the unusually deep drilling process can cause the drill to wander off course as the block has a variety of materials both soft and hard!

Excellent quality for plaster board and brick walls

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

As suggested by the title, this purchase was a biy of a long shot. I was looking for something sturdy to mount our sunday fun day apparatus to the dot and dab dungeon wall. 8 screws with the capacity to support a maximum of 100kg, I thought I'd give it a shot. Since the Mrs lost weight, she's well within the 100kg max limit. And with my own 2 legs taking up the majority of the carrying capacity, I secured our kit with a mere 2 screws. Ballsy move I admit. But it seems it has paid off. So far the fixings have been able to withstand a rigorous 3 minute work out. Currently in training to achieve 4. What will give up first, the screws or the stamina?

These fixings are a game changer for securing heavy fittings to plasterboard. Will only buy these now

So I'm a plumber, everyone wants tall deco rads now and these are perfect for them on dot an dab walls. Also hung a few boilers & my own TV at home 👍
