Prevent the metal roof from bending due to the upper screw effect.
This is a self-tapping drilling screw that can fasten steel plates in a single process. The "CR type" has a steel body, a washer made of hot-dip galvanized steel plate, and a neoprene packing. The "SCR type" has a stainless steel head cap, a steel body, a stainless steel washer, and neoprene packing. The head shape is hexagonal, making it suitable for overlapping metal roofing. The packing uses neoprene, which is impregnated with a special resin on felt that does not drip tar, making it ideal for areas requiring waterproofing.
