1. Product Name & Standard Official Name: Cross Recessed Pan Head Self-Tapping Screw Standard: DIN 7981 / GB/T 845 / ANSI B18.6.3 2. Structural Features Adopts pan head design with a smooth rounded top and flat bearing surface. Phillips cross recess drive for efficient torque transmission and easy installation. Features full-thread shank with a sharp, self-cutting pointed tip (with cutting notch). Precise thread rolling for smooth driving into materials without stripping. 3. Material & Strength Grade Main material: Carbon steel (e.g., C1022A). Stainless steel available on request. Heat-treated to achieve high hardness and torsional strength for demanding applications. 4. Surface Treatment Common finishes: electro-galvanizing (clear/blue-white zinc, as shown), white zinc, yellow zinc, black phosphating, Dacromet, and nickel plating. Custom anti-corrosion coatings optional for different environments. 5. Key Advantages Pan head provides a large bearing surface to securely hold thin materials without pull-through. Phillips drive allows high torque transfer and minimizes cam-out. Sharp pointed tip with cutting notch enables rapid self-tapping, reducing the need for pre-drilling. Full-thread design ensures strong holding power and pull-out resistance. 6. Application Scenarios Extensively used for wood fastening, plastic assembly, light gauge sheet metal connection, furniture installation, electronic enclosures, and general light-duty repair and DIY projects.
