Because tapping screws must deform or cut the material into which they are installed, their metallurgical composition is strictly regulated. ASME B18.6.4 stipulates that carbon steel tapping screws must undergo case hardening. This process creates a highly wear-resistant outer surface (to maintain thread integrity during driving) while preserving a ductile, resilient inner core to prevent brittle structural failures under tensile loads.
