The screw is 100mm long and 5mm across the maximum diameter of the threads with the head maximum diameter being 10mm.

Tested to 250kg (without failure) on four fixings with a safe working load of 73kg, it is ideal for heavy loads such as TVs and wall cabinets. For heavier stuff I use Corefix, these go through the plasterboard and right into the solid wall with an internal strengthening collar to bridge the gap. Corefix is a unique heavy duty fixing system for dot and dab wall construction, a method used almost exclusively in the UK’s new build homes. With the screws (5 x 100 mm) provided you can only mount things up to 10 mm thick on the wall but with longer screws (I bought some 5 x 120 mm) you can do up to 30 mm.I've used them to secure Venetian blinds inside window recesses with dry lined walls over thermalite blocks (side mounted as I couldn't screw up into the window lintels). This means that Corefix can safely support heavy loads – 100kg (independently tested) and over 200kg in-house tested. Because these fixings have been especially designed to provide a secure fixing into exactly these types of internal walls. If your plasterboard wall is of the dot and dab wall type, then definitely yes you can fix your boiler and radiators to that plasterboard wall if you use the right type of plasterboard fixings and for us that means Corefix.

Steel core for heavy duty use: Designed for heavy-duty use, these plasterboard over blockwork wall fixings include a steel core for reinforcement to provide a solid, reliable hold.No matter your experience level, the straightforward design is quick and easy to install with only a drill, hammer and screwdriver. A stud wall or stud work wall – is where a wooden frame is constructed to create the room partitions and the plasterboard is then attached to the framework. Initially designed for hanging heavy kitchen cabinets, it is now widely used in the plumbing and heating, kitchen, bathroom and DIY sectors.

They are exceptionally easy to use, feel totally solid and secure and I was very impressed with the look and quality of the 3 components.

However make sure that you have sufficient space between the plasterboard and the wall behind it to allow the fixing to be inserted fully before opening out. This is because Corefix – unlike other typical rawl plug based fixings – will bridge the gap between the plasterboard and the solid wall behind it, thus spreading the load and ensuring a strong safe fixing. To give you more peace of mind, Corefix has been independently tested to 100kg loading and has safely held 250kg in our own internal tests. I've had better success with plasterboard fixings than I expected; they can actually take a fair amount of weight. I used Corefix Air fixings to hang and secure new kitchen wall cabinets to a dot and dab over aerated concrete block wall.

For my ikea wall rail for pantry units, then 8cm screws that pull up tight would be fine probably as you say. Corefix 120 (yellow) has a longer 120mm screw for securing fixtures of up to 30mm deep (eg wooden battens).

Fischer DuoPower and the blue coloured Rawl 4 All both spring to mind… Have I just outed myself as a wall plug nerd? If your plasterboard wall is a dot and dab wall, then yes definitely you can fix your kitchen wall cabinets to that wall, but only if you use the correct type of wall fixings and for that we recommend Corefix. The best fixings to use for a dot and dab wall, where a heavy load is going to need to be supported, would be the Corefix fixing.and I’d worry in the event of a child pulling/wobbling event, and play in the fixing may slowly bring it loose. Corefix is not reliant on the strength of the plasterboard - instead it transfers the load directly to the solid masonry behind via the steel core.
