About this product

This Grade 12.9/10.9 Hex Flange Head Concrete Screw Bolt is engineered for robust and reliable fastening in concrete applications, serving as a high-strength anchor solution. Its primary function is to securely attach fixtures and structural elements to concrete substrates with exceptional load-bearing capacity. Key features include a hex flange head design for superior torque application and a self-tapping thread profile that ensures efficient and strong engagement within the concrete. Constructed from premium carbon steel materials such as Q235, 35K, 45K, 40Cr, B7, and 20MnTiB, as well as A2/A4 stainless steel for enhanced corrosion resistance, these bolts offer superior tensile and shear strength, characteristic of their 12.9 and 10.9 grades. The construction quality is paramount, ensuring durability and long-term performance in demanding environments, with available finishes to suit specific project requirements. While specific size ranges and customisation options are not detailed, the availability of multiple steel grades suggests a versatile product line. Typical applications span the construction industry, including structural anchoring, facade installations, and securing heavy machinery. Target buyers include importers, wholesalers, and construction companies seeking high-performance concrete anchoring solutions. These bolts are suitable for international trade due to their robust construction, adherence to high-strength material standards, and broad applicability across global construction projects.
