Engineered for Strength – How Corefix Connect Works

Corefix Connect stands out due to its unique engineered steel core, designed specifically for dot and dab walls. Unlike standard plasterboard fixings, which rely on drywall anchors in the plasterboard material to hold, Corefix Connect’s steel core transfers the load directly into the solid blockwork behind the plasterboard. This eliminates the risk of plasterboard crushing and ensures a secure, long-lasting hold for heavy items like radiators, boilers, and TV brackets.

The fixing consists of a heavy-duty wall plug and a precision-engineered steel sleeve that bridges the void created by the dot and dab adhesive. This means that when you screw into the fixing, the load is evenly distributed and anchored into the blockwork, providing unmatched strength and stability.

The Best Dot & Dab Wall Fixings for Heavy Loads

UK tradespeople choose Corefix Connect because it holds serious weight with its 55kg Safe Working Load per fixing (Factor safety of 2). For example, a plumbing and heating engineer described in a Screwfix review how he’s used these fixings to secure heavy radiators and boilers without any issues. Another tradesperson described Corefix Connect as “the best dot & dab plasterboard fixing” after using them for TV brackets, towel rails, and shelf brackets.

A maintenance professional highlighted how Corefix Connect successfully secured double column radiators to converted garage walls. With a steel-reinforced core, these fixings ensure your load is anchored to the blockwork behind the plasterboard, rather than relying on weak drywall anchors.

Fixing That Lasts – No More Failures

Many professionals have tried and failed with other plasterboard fixings before switching to Corefix. A landscaper recalled how a handyman installed a banister using basic plastic wall plugs, which quickly failed. After replacing them with Corefix, the banister was “firmly anchored to the blockwork” and built to last.

Similarly, a builder and multi-trader praised Corefix for allowing him to fix “heavy mirrors, TV mounts, and wet towel rails” without worry. These fixings were described as “bombproof” by another user who mounted a 60-inch TV and heavy curtain rails with complete confidence!

Easy to Install, Built to Perform

Corefix Connect isn’t just strong – it’s easy to install. Just drill a 10mm hole, tap in the plug, insert the steel core, and screw in. A home DIYer who mounted IKEA kitchen cabinets appreciated how the length was perfect to bridge the dot and dab void and secure into the brickwork behind.

Even a DIYer was amazed by how simple the process was when installing a TV bracket: “So easy to do and the TV is still on the wall!” And another customer found them ideal for securing curtain poles, ensuring they don’t loosen over time.
