Will definitely use in future on dot and dab walls. Review: Great product - I spent some time shopping around and researching what I could use to hold a heavy shelf up to a plasterboard wall. My wall had 27mm insulated board, dot & dab, then brick. I fitted the plasterboard myself, and had squashed it on the wall quite hard, so little gap. I chose these plugs because I estimated there was at least 35mm from the finished surface to the brick. Even a 70mm plug would not have been anchored enough. I was impressed with the simple idea of inserting a metal core to provide strength, and never doubted that these would work. I had to buy the 120m length screws, as the shelf brackets were 15mm thick. I would say fitting them well, takes some skill and is not for an amateur. I used a small pilot bit to get my holes precise. Then an average 10mm masonry bit, will not be quite long enough to drill the hole, so either a long one, or not fully in the chuck for the last 8mm. I then had to use a long 6mm to make the hole slightly deeper, as the 120mm screws would need to go in further than the back of the plug (bracket 15mm thick). You need to be careful to clean the hole out, I used a screwdriver as if the dust gets packed in the end, the plug wont sit home. You can tell if a plug is not going to sit home, and if you are careful you can pull it out and improve or clean the hole. The screws are good quality. Hammering in the metal insert is very satisfying. I only had 2 issues. One hole must have caught a mortar joint, and was slightly off from the plasterboard hole. These plugs do not bend, so had to ream out the p'board. In tackling this, I broke one of the plugs just using moderate force to push it in. my only criticism of these plugs is that the final part near to the flange of the plug is fairly weak - due to cut outs for barbs. There is probably only 50% plastic remaining after the cut outs. Given that its not easy to get these holes 'just right' it would be nice if this part could be improved to allow a bit more robustness when fitting. I'm sure the damaged ones in other peoples reviews / photo's will have been due to not cleaning out the hole and hammering them until they crush. When fitted properly the flange sits a little proud from the wall, but not really noticeable and gives you something to clamp against. The only other issue is that it is hard to get holes in precise places, with a 10mm drill bit. If you don't have any adjustment on your fixing, then you need to take your time and be very careful. I ended up enlarging some of my bracket holes to compensate for the misalignment being a shelf with 4 brackets, it needed to be perfect. A TV mount wouldn't pose this problem. In hindsight, I should have taken my pilot hole into the brick, but I only went through the p'board. I would use again, without a doubt. Great product. ## Features - STEEL CORE FOR HEAVY DUTY USE: Patented design allows for heavy-duty use, these dot & dab plasterboard wall anchors include a steel core for reinforcement to provide a firm, reliable hold.

Also depends on number of screws/fixings needed as I believe the 250kg is between four. **Q: Are these exactly the same as the 100mm, apart from the length? I have a dot dab wall which has been brought out quite far and tiled So need longer** A: As far as I know yes just longer screws maybe a different colour box, I used them to fix a thicker timber support to the concrete behind a 40mm kitchen wall. Only used a few so will likely get some 100mm screws to use with the rest of them as well. **Q: Will these work on Celotex 50mm with 12.5mm plasterboard?** A: I have used these on dot and dab plasterboard on a blockwork wall but would not recommend for a plasterboard stud wall as the plug would not be supported for the full depth. For fixing to plasterboard alone I use a “steel hollow wall anchor”, Diall or Fischer are good brands. Good luck **Q: Hi can these be used to fix insulated plasterboard to a brick wall?** A: Yes this is what they are made for. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Best Fixings available! *by A***R on 11 June 2026* Really strong fixings, easy to install, used for various projects and never had an issue.
