Get some 6mm ones if you're using a 6mm bit also make sure you're drilling deep enough for them to actually fit and don't forget it should be a relatively snug fit.
It's a firedoor. I started with a braddle, then a pilot bit (my 4mm) then the 6mm.
Actually, maybe I didn't drill far enough in yet? The screws drop all the way in the hole I made though without the plug. See, last night I tested the different size bits on a piece of wood and the red plug pushes all the way into the 6mm hole. So maybe I should drill a bit deeper?
Lol, I'm really quite hopeless at DIY but I do at least try.![]()
