The SFS TDA-S-D16 is a premium full 304 stainless steel facade panel screw engineered for attaching fiber cement, HPL, composite, and other cladding panels to aluminum and steel substructures. Its dual-thread design delivers strong fastening performance across a wide range of substrate thicknesses while providing long-term corrosion resistance.

Featuring a low-profile 16 mm dome head with a T25W drive, the TDA-S-D16 provides a clean architectural appearance for exposed fastener applications. The larger dome head increases bearing surface for improved panel support, while color-matched Vista spray finishes are available to coordinate with facade panel colors.
