Noob here, potential silly question alert. Planning to make a fitted cupboard in an alcove when sufficiently informed For the frame I've seen people place timber against the wall, drill through it and into the brick at once, tap a plug all the way through and screw. I plan to use a 7mm drill, brown plug and 5mm screw but I don't quite understand... as the hole in the batten is bigger than the screw, none of the thread will make contact and it's secured only by the head which is 10mm. Is that secure enough...? Cheers!
