    Hi, which wall plugs should I use for these screws? I'm thinking to use the red ones. 20200921_133432.jpg

    Red definitely. If possible use a 5.5mm drill. Make sure the plug is well into the wall - head at least half the thickness of the plaster(board) into the wall.

    I don't have 5.5. Should I first use 4mm, then use 5mm? Or should I just use 5mm? Also what do you mean by head at least half the thickness?

    Look like cheap plugs, reds possibly 6mm?

    Usually red = 5.5mm, brown = 7mm. Less 0.5mm if the wall is softish or crumbly. Too large and the plug will spin in the hole

    Well have drilled the wall. I suggested 5.5mm drill as the plug will fit into the hole tightly. With a 4.5mm screw you get a more secure fix with the plug in the fractionally smaller hole.

    The head (top) of the plug needs to be under the surface of the plaster finish by at least half the thickness of the plaster(board) - that stops the plaster from cracking, makes for a more secure fixing as the plug and screw are in more brickwork and makes covering up when the screw is removed in the future easier to hide.
