Baven 25Pcs Metal Cavity Anchor Wall Plasterboard Plug Fixing Screw Hollow Wall Expansion Anchors, Hardware Tools for Wall Concrete Plasterboard- M4

Expensive for won’t they are.

Does what they are meant to

I bought these with the intention of using them to put up a shelf on a plaster board wall. There is a very small amount of thread on them which becomes non existent after they have been put into the wall so the screws have nothing to grip on to and just slide in and out. Thankfully the cheap, thin metal they are made from could easily bend and snap so I could pull the heads out of the wall and push the inner part in-between the walls and then start again with some decent sized Fischer ones. Avoid!

Very poor quality

Bad quality. Some screws couldn’t be unscrewed without damaging the anchor, some snapped as I was installing them. Avoid.

Not strongJust snaps off while fitting on the wall

some of the fixings were not the best poor quality but did the job
