Self Tapping Screws

  • Self Tapping Screws

Self Tapping Screws or "sheet metal" screws as they're typically called, are normally Type A, Type AB, or Type AB tapping screws used in thin metal or resin-filled plywood. Type A self tapping screws have somewhat of a sharp point and have wider spaced threads than a type AB self tapping screw.

Type B self tapping screws are sheet metal screws with a gimlet or blunt point and are used in molded or through holes in thin metal, non-ferrous castings, plastics or resin-filled plywood.
