Okay that title didn't quite come out right. Here's the thing, I look through the screwfix catalogue and find tons of screws for wood, masonry, speciality. But what about bog standard screws for putting into a wall plug ? I found self tappers but that just doesn't seem right, is there a specific screw for wall plugs a sort of jack of all trades ? can a wood screw be used with a wall plug ? are razor sharp, twin shanked, ribbed countersunk wax coated screws suitable ? seems like overkill to me.
