Bimetal composite drilling screw is corrosion-resistant stainless steel Pointed cut tail wood drilling screw, ，screw head and locking (18-8) Austrian stainless steel body system material; Alloy steel (carbon steel) is used for the tapping part and the end drilling part, and the surface is specially treated. Corrosion resistance life can achieve good results. Because the thread drilling tail and tapping area are through special hardening treatment of metal, when the steel plate into the stainless steel part of the introduction of thread, excluding the past stainless steel tapping screw often because of thread wear deformation and locked phenomenon, to achieve the conclusion, and keep high coefficient of drawing strength.
