Engineered for heavy-duty construction and industrial applications, our Hex Head Self-Drilling (Tek) Screws are available in carbon steel (hot-dip galvanized) or stainless steel 304, offering unmatched corrosion resistance and durability. Featuring a self-drilling tip for metal penetration, a hex head for high-torque installation, and robust coatings, these screws eliminate the need for pre-drilling in steel, wood, or composite materials. Ideal for roofing, cladding, steel framing, and marine projects.
