Truly Heavy-Duty – Reliable Fixing Solution for Plasterboard Walls
I’ve tested many drywall and plasterboard fixing kits over the years, and Bullfix absolutely stands out as one of the most robust and reliable I’ve used—particularly for dot & dab walls and hollow cavities. ✅ Built to Handle Serious Weight I used these to mount a large 32" bathroom cabinet onto a hollow plasterboard wall. With typical fixings, I’d be nervous. But Bullfix lives up to its name—the design spreads the load beautifully, and once installed, there’s no wobble, no stress cracks, and zero movement. ✅ Versatile and Works Where Others Fail These aren't your average wall plugs. They work across dot & dab, stud walls, and standard cavity walls with excellent grip. In fact, I tested one with a pull force gauge and it held firm under load where cheaper fixings failed or pulled through. ✅ Easy to Install The pack comes with screws, and the fixing itself is simple to insert using standard tools. Once it’s in, it opens up behind the board and anchors itself solidly. No special drill bits, no faff. ⚙️ What’s in the Box 8x Bullfix heavy-duty anchors Screws included Clear fitting guide (surprisingly helpful and well-illustrated) ⚠️ Tip: If you're mounting into very crumbly board or using particularly heavy shelves, I’d still recommend using a batten or spreading the load—but for most standard installations, Bullfix can hold its own without reinforcement. ✅ Final Verdict Outstanding for wall-mounted TVs, heavy mirrors, cabinets, radiators, and more. If you're looking for peace of mind on plasterboard, skip the plastic plugs and get Bullfix. Worth every penny for safety and simplicity.

Cons: Some users have reported that the fixings can be a bit difficult to insert into hard plasterboard. The fixings may not be suitable for fixing heavy items to very thin plasterboard. The fixings may not be suitable for fixing items to uneven surfaces. Overall, the Bullfix Extra Heavy Duty Plasterboard Fixings - 24 Pack, Drywall Anchor, Wall Plug Alternative for Dot & Dab, Plasterboard Wall Plugs, Stud Wall & Hollow Cavity Wall Anchor, DIY Kit with Screws are a great option for fixing heavy items to plasterboard walls and ceilings.

Here are some additional tips for using the Bullfix Extra Heavy Duty Plasterboard Fixings:** Make sure the fixings are inserted into the plasterboard at least 45mm deep. Use a level to ensure that the fixings are inserted straight. Allow the fixings to dry completely before hanging any heavy items. Do not overtighten the screws, as this can damage the fixings.

Great product
Brilliant product, put a electric fire up weighing 50kg, these bad boys did the trick on a stud wall.

Seems to hold heavy objects well
Use these Bullfix Extra Plasterboard Fixings for heavy tall kitchen cupboards on a narrow partition wall. Used four fixings, two on each bracket and all seems fine even with cupboards loaded with a heavy pottery dinner set. A little expensive but works well.

Very strong fixings and easy to install
Used to mount a 65" Hisense QLED TV to a dot and dab plasterboard board wall. 3 along the top and 3 along the bottom of an Elived full motion bracket and it's absolutely solid and going nowhere. Just make sure you have enough space between the plasterboard and the wall to allow the legs to go into the gap and then grab the rest of the plasterboard when tapped into place. So easy to fit, use a 20mm spade bit to cut thru the plasterboard, tap home the retaining ring into the gap, pop the grab legs into the hole/ring and tap the legs open with a hammer. Job done. Mount whatever you want to mount with the supplied screws.

Had high hopes for these...
I needed to hang a fireplace and TV on a plasterboard wall. I've never done this before so wanted to get something strong enough. These came recommended by several family members so I bought them. The drill bit that comes with them is great (who wants to have to buy a separate drill bit right?), and the plugs themselves were easy enough to figure out, even for a novice like me! However, after drilling a 20mm hole in the wall, I discovered there wasn't enough clearance behind for the plugs to go in and do their stuff, so basically, they're useless to me! Had there have been enough clearance, these seem like they would have been great.

Perfect for IKEA floating shelves on plasterboard
Absolutely brilliant bit of kit. Ordered these for IKEA floating shelves, and they're superb. So easy to fit, feel very reliable, and are now my go-to for any plasterboard fixings that need to be reliable enough for weight. Brilliant 👏🏻

I purchased and installed these in March 2025 and used them to mount a grab bar in drywall. They were easy to use and have held up very nicely. Considering this use is a more direct pull (not shear), they hold and show no sign of pulling out of the drywall. It may not be a recommended use, but I was in great need of assistance for a disabled person. Please proceed with caution, but for me, they have worked great. I do not know of any product that could have fulfilled that need - priceless!

This product works amazingly well. Super strong and secure fixiture, prevailing where others had failed and weakened the drywall. Highly recommend.
