Welcome to Hefei SENOTECH New Materials Co., Ltd, a trusted trading partner based in Hefei, Anhui, China since 2020. With an annual export value exceeding US$1 million and a global reach spanning North America, South America, Europe, Southeast Asia, Africa, Oceania, and the Middle East, we are dedicated to supplying high-performance fasteners that meet international standards. Our C1022A Carbon Steel Wood Screws with Ruspert Coating are specifically engineered for demanding applications in MDF and plywood. Featuring a unique double countersunk head, half thread design, and high torque capacity, these screws deliver exceptional holding power, reduced splitting, and superior corrosion resistance—ideal for professional woodworking, cabinetry, furniture assembly, and construction projects.
Below, we detail the key specifications, benefits, and technical data that set our C1022A wood screws apart from generic alternatives.
Product Features & Technical Specifications
- Material & Coating: Made from high-quality C1022A carbon steel (through-hardened) with a Ruspert coating—a multi-layer anti-corrosion system offering excellent resistance to moisture, chemicals, and outdoor exposure. Ideal for both indoor and damp environments.
- Double Countersunk Head: Combines a flat underside and a bugle top profile, allowing the screw to sit flush or slightly recessed in the workpiece. Reduces material stress and improves aesthetic finish, especially in MDF and plywood surfaces.
- Half Thread Design: The upper portion of the shank is smooth (unthreaded), while the lower portion is fully threaded. This design enhances clamping force and prevents pull-through, ensuring a tight joint without stripping the threads in soft materials.
- High Torque Capacity: Optimized heat treatment and geometry provide superior torsional strength, enabling the screw to be driven without breaking under high pressure. Suitable for power tools and production-line assembly.
- Self-Tapping Sharp Point: The sharp point eliminates the need for pre-drilling in most softwoods, MDF, and plywood, saving time and labor.
- Drive Compatibility: Available with Phillips or Pozidriv recess (upon request), ensuring compatibility with common screwdriver bits.
