In corrosive environments, bi-metal screws can withstand the elements with a stainless steel head, but still offer a strong carbon steel driving point. Created with innovative manufacturing processes and product designs, they can increase speed during the driving process and hold materials together through it all. In coastal geographic regions, and other areas affected by humid environmental conditions, stainless steel has been proven to be the best material to resist rust and degradation. However, carbon steel has the best performance in a wide range of applications requiring self drilling screws. Created with advanced manufacturing methods in Taiwan, stainless and carbon steel materials are carefully combined to create a screw with two types of materials, taking advantage of all the strengths of each type of steel.
