Stainless steel pozi pan self-tapping screws, packs of 50. The 90mm x 6.3mm is for ridge caps, hip caps and verge, going through the cap and roll into the timber. The 32mm x 4.2mm is the tile fixing screw for pitches between 12.5° and 25°, where Envirotile calls for screws rather than nails. Above 25° the tiles are nailed with stainless annular ring shank nails.
