Jan 24, 2017 at 14:19 comment added microlambert Thanks to all for the excellent comments. To address the mystery of how 7mm plugs went into 6mm holes: although the drill bit was 6mm, I suppose that in the process of using a hammer drill to go into the masonry, I ended up with holes that were slightly bigger. The plugs went in snugly (albeit with a bit of encouragement from a hammer in some cases).
Jan 24, 2017 at 11:15 comment added Agent_L I am amazed on how he managed to drive 7mm plugs into 6mm holes.
Jan 24, 2017 at 3:47 comment added alephzero @JDługosz the 6mm hole is too small for a brown plug. The hole is already too full of squashed plug, so there is no room for the screw.
Jan 24, 2017 at 2:36 comment added JDługosz How is a 6mm hole too small if 4mm is the right size?
Jan 23, 2017 at 17:55 comment added DMoore While I agree with your size assumptions it is normal practice (for me at least) to use a bigger screw than the hole. I have had way less issues with screws becoming loose doing this.
Jan 23, 2017 at 15:19 comment added RedGrittyBrick @JPhi1618: I expect it's just that a few major brands have followed a convention established by the market leader.
Jan 23, 2017 at 15:04 comment added JPhi1618 This is interesting. Is there some color standard in the UK that all wall plug manufacturers adhere to?
