Catalog number: HSP430 Features: ●The inclined insertion angle is 12°, the highest in the industry. ●This drill screw can be driven into curved surfaces such as pipes. ●This drill screw can drill, tap, and tighten holes in steel plates all at once. Applications: ●For fastening metal fittings and steel plates. Specifications: ●Compatible driver: Phillips No. 2 ●Nominal dimensions (mm) d x L: 4.1 x 30 ●Nominal dimensions (mm) D: 7.8 Material/Finish: ●Stainless steel (SUS410) Surface treatment: Passivated Note: ●A driver drill (with clutch function) is recommended for driving stainless steel drill screws. ●Stainless steel has low thermal conductivity (heat is difficult to escape) and high thermal expansion coefficient, so frictional heat during driving is difficult to escape when stainless steel drill screws are driven, and when driven with "high rotation" and "high torque", the screw expands due to heat, making it prone to "burning" and "breakage".
