Bi-Met 300? screws-Super anti-corrosion
Bi-Metal screws are combined by SS304/316 with 435 alloy steel that are leveraged their differing strengths.
The utilization of the hardened, carbon steel tip and lead threads eliminate the need for pre-drilling and give way to fast, easy application. This allows builders to use only one tool instead of two, subsequently driving down installation time, labor costs, and tool maintenance costs.
Not all stainless steel is created equal. While all offer some degree of corrosion resistance, none matches the protection of 300 series metals. This includes the ever-popular 400 series steels; though suitable for some applications, it is vulnerable to Hydrogen Assisted Stress Corrosion Cracking (HASCC) and can develop harmful rust with prolonged exposure to harsher elements.?This jeopardizes the integrity of the screw’s connection by weakening
For this reason, SFS engineered its ultimate self-drilling bi-metal fastening solution using 304 stainless steel, resilient enough to stand up to dissimilar metal connections, pollution, and highly corrosive environments without compromising connection integrity.
