ST-04 Tapping Screw Specification for Ductile Metals and Plastics
The ST-04 tapping screw forms its own mating thread when driven into drilled, punched or cored holes in ductile metals and punch-extruded metals, and into soft materials such as plastics and sheet materials.
ST-04 tapping screws cover M2.9 to M6.3 (#6 to #14) and 9.5 to 150 mm, with flat or pan heads, a Phillips drive, and blue zinc or yellow zinc finishes. List the required screw material with the specification in the inquiry, so the quotation matches the application.
