Review: The Ultimate Fixing Solution for Drylined Walls! - If you’ve ever struggled with securing heavy items to drylined walls, Corefix is an absolute game-changer! Unlike standard wall fixings that risk crushing the plasterboard, Corefix secures directly into the solid wall behind, giving incredible strength and stability. I used these to mount a large wall cabinet and a heavy radiator, and they performed flawlessly. 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 used If 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!
Review: Strong and reliable - Used them to mount a heavy shelf. Our house is old and the plaster is basically dust at this point so we needed something heavy duty. These longer plugs get right into the brick and secured the shelf perfectly. Really easy to use. Great idea with the metal inserts ensures the screw doesn’t deviate. Screws seem to be tough and great quality. Highly recommended

## Questions & Answers

**Q: what's the difference betrween Corefix and Corefix Plus30?**
A: Thanks for the  question Pamela, the difference between the fixings is as follows: 

Corefix Original (Red) is the standard go to fixing for installations where the fixture thickness is up to 10mm (eg metal brackets). Independently tested safe working load of 100kg on 4 x fixings

Corefix Air (Blue) has been created to highlight the suitability for use when fixing into thermalite/aircrete blocks as this type of wall construction is notoriously difficult to fix to. Independently tested safe working load of 73kg on 4 x fixings in thermalite/aircrete blocks.

Corefix Plus30 (Yellow) has a longer 120mm screw for securing fixtures of up to 30mm deep (eg wooden battens). Independently tested safe working load of 100kg on 4 x fixings

All Corefix fixings have high load ratings and performance and are suitable for use in all types of brick and block, including lightweight/aircrete blocks.

I hope this helps you make an informed decision moving forward. Kind Regards the team at Metex

**Q: Best size bit to use Length and diameter?**
A: The bit size is 10mm, noted on the side of the packaging and in the product description on Amazon.
The length of the bit depends on the depth of the gap and length of the fixing. 
Watch this video from Skill Builder where he uses these fixings and mentions the drill length.
Hope this helps

**Q: Are these suitable for fixing a curtain pole?**
A: Yes, they are rated to carry 200kg weight I think, so curtain pole will be no issue. Perfect if you have dot n dab wall construction as the metal sleeve carries the weight to ensure plasterboard won’t crack.

**Q: Can corefix be used with lath and plaster walls?  I an thinking about drillin through the lath and plaster and mounting the corefix into the brick.**
A: Can’t see why this wouldn’t work. The point of the fixings is to bridge the gap between plasterboard and breeze block behind it in modern construction properties. So long as the gap between the lath and plaster and the block work behind is not too big then it should work in a similar way I’d think.
