Bi-metal Screw

 Our latest Bi-Metal screw combines series 300 and series 400 stainless steel  in response to the fact that traditional Bi-Metal screws could not be penetrated series 304 stainless steel plate.

With its great penetrating capability and stability,that the new Bi-Metal screw can penetrate series 300 stainless steel plate of 0.5mm~6.0mm. 

Instead of the heat treatment of entire screws, which would reduced the tensile and torque performance of series 304, we insist on manufacturing with high-frequency induction hardening to maintain the high tensile and high torque strength of series 304.
