TIMco Corefix Radiator & Boiler Plasterboard Fixing Kit - Red - 5.0 x 100mm - Pack of 6

The product information does not specify a maximum weight limit but emphasizes its suitability for 'secure heavy-load anchoring' and 'superior holding power' for items like radiators and boilers, implying a high load capacity when installed correctly into a solid substrate.

This fixing has a Corrosion Rating of 1, meaning it is intended for clean, dry, and low humidity environments. It is not recommended for areas with high moisture levels like bathrooms or steamy kitchens.

You will need a 10mm drill bit to create the hole for the Corefix insert.

No, only standard tools are required: a drill, a 10mm drill bit, a hammer, and a screwdriver.

The zinc-plated steel tube insert bridges the cavity created by dot and dab plasterboard construction, anchoring directly into the brick or block substrate behind the plasterboard. This provides a much stronger and more reliable fixing than relying on the plasterboard alone.

The kit is designed for plasterboard installations, particularly those with a cavity (dot and dab) or supported on battens, where anchoring into the substrate is crucial for heavy loads.

The kit includes 5.0 x 100mm screws designed to work with the Corefix inserts.

Ensure the Corefix insert is fully seated and flush with the plasterboard. Verify that the drill hole was the correct 10mm diameter and that the substrate behind the plasterboard is solid. Check that the screw is aligned correctly with the insert.

Confirm the drill hole is clean and clear of debris. Ensure the insert is being hammered straight and not at an angle. If encountering significant resistance, check for obstructions within the cavity or substrate.

Re-examine the installation steps. The primary cause of instability is often incomplete anchoring into the substrate. The insert should firmly grip the material behind the plasterboard.
