Corefix can be installed in less than one minute, without the need for specialist tools – all you need is a 10mm masonry drill, hammer, and a screwdriver: Using a 4-inch wall plug, with the main body of the plug at a 10mm diameter, the Corefix wall plug is pushed into a 10mm hole. It is not pushed through the plasterboard however as the lip at the head of the plug will prevent that happening.

This downside however, is nowhere near as common as the problem of trying to fix heavy objects such as large flat screen TVs and kitchen cupboards to a dot and dab wall. The diagram shows what Corefix can hold and 250kg is almost 39.5 stone or 3/4 averagely built people – That is very impressive indeed. How and Where do I buy Corefix?The steel tube, as you can see from both the video and the image below, bridges the gap in the dot and dap wall. 50% of the steel tube is held in the masonry which is how the load is supported at the other end of the screw. Remove any dust or debris from the hole before gently tapping the Corefix plug into place until the flange sits against the plasterboard.

This is the number one problem with using ordinary plugs and screws to a dot and dab plasterboard wall. How Does Corefix Work? This can result in cold spots on the wall which, in turn can result in condensation and condensation around the window reveals of a dot and dab plaster boarded room is very common. If you need to secure deeper fixtures, then we recommend the Corefix 120 Dot and Dab Wall Fixing, which has a 120mm screw length. Because it is bent, the downward force of the attached object starts to tilt outward as the image above shows. This stops the force being 100% downwards and moves it to an angle which, after time, starts to pull the screw out of the wall. Once the plug is in the wall, a steel tube is pushed into the end of the plug. This tube is hollow and very very strong. It is long enough to go right through to the masonry wall where it, after being hammered home, forms a really tight fit about 25mm into the masonry wall.This clearly depends on the size of the television but with all the major brands such as Sony, Samsung & Panasonic all making flat screen TVs up to a staggering 100 inches and above in some cases, it really is important to know the weight of your TV and know your hollow wall plasterboard fixing will support the load. Below are some approx. weights for standard size wall mounted flat screen TVs* A screw, in this gap, is not supported and any heavy load applied to the end of it will cause the screw to bend.
