The diameter of that hole should be 2mm large that of the screw, to allow for thermal expansion movements. In case of dark coloured sheets pre drill even large holes, and use wider fastener washers.Use of self-tapping or self-drilling screws is recommended. In case of wooden structures,suitable wood-screws should be used. All the screws should be corrosion resistant,with at least heavy-duty hot-dipped galvanised finish,or stainless steel if used in an extremely corrosive environment).
