Improving the Physical Properties of 302 Stainless Steel Tapping Screws 800454

The purpose of this paper is to introduce a 302 stainless steel tapping screw which has improved strength and hardness and will meet the performance requirements found in SAE J933b, a qualifying test for case hardened carbon steel self-tapping screws. The new screw called a COREX GX tapping screw incorporates special processing techniques, along with a modified tapping point which makes possible its use in tapping carbon steel where conventional 300 stainless steel tapping screws have failed.
