I've just bought some Screwfix 32mm, self drill metal plasterboard fixings branded EASYFIX, like below:-
I have now used 9 of these in a plasterboard (Paramount) wall. 5 have proved impossible to install and have made a mess of the wall. This is a near 50% failure rate! The screws that come in the box have to cut their own threads into the metal fixing as they are tightened. The metal is quite resilient and it takes a great deal of effort /torque to finish the screw. As you apply a lot of torque to drive home the screw, the entire metal fixing continues to rotate in the plasterboard. It eventually either drills right through the plasterboard layer, or strips the plaster thread and just spins. You end up with a large hole either way, and the fixing has to be withdrawn with pliers.
I can't understand how to use this fixing. 22 Screwfix reviews give this product 4½ stars. I have some 'O' levels and thought that I'd be clever enough to use such a fixing, but it seems I'm still not smart enough. Could this be a dodgy batch? I'd give the fixing 1 star myself. What am I missing..?
PS. This seems similar to this thread for another Screwfix product.
