TimCoM4 x 38mm HEAVY DUTY METAL PLASTERBOARD CAVITY WALL FIXINGS ANCHORS PLUGS (20)

These are very sturdy, and once they are in and clamped will not move. Very strong and great for things like curtain pole fixings etc. But, once they are in they are almost impossible to remove without destroying your wall, so only use for permanent jobs.

If you have typical plasterboard hollow cavity walls these things are a great option if you are putting up shelves or something that needs a decent fixing. Check no wires/pipes etc behind the intended drill location, make a pilot hole then the proper size hole for the fixing, tap it in with a mallet all the way and 4 little prongs bite in to the wall surface (gripping the fixing nicely against the front of the plasterboard). Use a retraction tool (or you could use pliers but carefully) and retract firmly the screw that's in the fitting which causes the metal body to unfold up against the back of the plasterboard then take out the screw and screw on your shelf etc. Rock solid. More reliable than plastic type rawplugs that sometimes get loose etc.

Great anchor bolts used them with fixings on floating shelves and bathroom towel rails into plastboard walls , easy to tap in and tighten well with electric screwdriver to start and finish with manual . Purchased several times . The small pack is handy if you only have a few things to secure for a good price

I bought 100 of these and at least 10 of them, the bolt pulled though and ripped the thread out when fitting with the fitting tool or the nut part separated from the main body, meaning removing the body and hoping it would drop down between the wall and plaster board so you could fit a new one. So about 1 in 10 gave me troubles. Once I had used these up I bought some Rawlplug ones from Screwfix and had no troubles at all

Easy to use and really hold
