Welcome to Hefei SENOTECH New Materials Co., Ltd — your trusted partner in high-performance fasteners. Our Self Drilling Screws for Steel Framing Hex Head Yellow Zinc Coated C1022A Carbon Steel are designed to deliver exceptional holding power and corrosion resistance for demanding structural applications. Engineered from premium C1022A carbon steel and finished with a bright yellow zinc coating, these screws eliminate the need for pre-drilling, significantly reducing installation time while ensuring a secure, long-lasting connection. Whether you are framing commercial buildings or assembling metal structures, our screws offer the reliability you need.
Key Features & Technical Specifications
- Material Excellence: Manufactured from C1022A carbon steel, case hardened for maximum strength and durability. This provides excellent thread rolling and drilling capability into steel up to 0.125" (3 mm) thickness.
- Hex Washer Head Design: The integrated hex washer head allows for high torque application without stripping, compatible with standard power tools and sockets. Ensures firm clamping force.
- Yellow Zinc Coating: A uniform yellow zinc plating offers superior corrosion protection, making these screws suitable for interior and protected exterior environments. Salt spray resistance up to 72 hours (test method per ASTM B117).
- Self-Drilling Point: The sharp #2 drill point (self-drilling tip) eliminates separate drilling steps, saving labor and tool costs. Ideal for steel-to-steel fastening in gauge 12 to 22 steel.
- Thread Design: Deep, sharp threads provide excellent bite and pull-out resistance. Threads extend close to the head for maximum grip in thin materials.
- Versatile Applications: Perfect for steel framing, metal roof decking, light gauge steel construction, HVAC ductwork, and general metal fabrication.
