In attempting to fix a toilet roll holder to a wall in my bathroom, the screw within the wall plug fails to tighten and grip the bracket. It does screw in but doesn't tighten against the wall. There are 2 holes and it's the same for both. I don't believe I over tightened when screwing in.
Both the wall plugs and screws were provided in a kit with the toilet roll holder so I know I haven't picked the wrong size. I also installed this same toilet roll holder in a different bathroom and had no problems.
What is the problem if the screw spins but the wall plug doesn't? Is there a way to resolve this problem without repairing the holes?
The screws are 35mm, the wall plug 25mm and I used a size 6 drill bit.
And yes, I am a complete newbie when it comes to DIY :). Many thanks,
