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.

Looks and works as described
brilliant idea. the slightly larger drill hole needed (a size that easily fillable) is more than compensated for by ease of removability and reuse

Strong
Strongest drywall fix I have ever used. Tip when installing, before putting in drywall, use the screw to pre-thread the hole to make install easier and not spin in the drywall.
