The Wing Tek is the Self Drilling Screw with the wings. The Wing Tek gathers drilling, tapping and tightening at the same time. The wing tek’s case hardness and core hardness is higher than the self tapping screw. The reason is wing tek has an extra function–drilling. In addition, wing tek needs to do the drilling test to make sure that the screw could drill the hole with the thread within the limitation time.
