SFS SX3-D16 Bi-Metal Self-Drilling Screw, Dome Head, 304 Stainless – #12 x 1-3/16″ (250 Pack)

The SFS SX3-D16 is a premium bi-metal self-drilling facade screw designed for attaching fiber cement, HPL, composite, ACM, and other cladding panels to steel and aluminum substructures. Featuring a corrosion-resistant 304 stainless steel head with a hardened carbon steel drill point, it combines long-term exterior durability with exceptional drilling performance.

The self-drilling point eliminates the need for pre-drilling in many metal applications, helping reduce installation time while maintaining outstanding holding strength. Its larger 16 mm low-profile dome head provides increased bearing surface while maintaining a clean architectural appearance. Color-matched Vista spray finishes are available to coordinate with facade panel colors.
