High Tensile Bolts: 8.8/10.9/12.9 Grade Strength for Heavy-duty Applications

M8 high tensile bolts, with a nominal diameter of 8 millimeters, are a popular choice for medium - sized fastening tasks. Despite their relatively small size, they offer significant strength, available in grades such as 8.8, 10.9, and 12.9, each providing different levels of tensile and yield strength. These bolts are commonly used in electronics manufacturing, where they secure circuit boards and components within enclosures, ensuring stability and protection against vibrations. In the automotive aftermarket, M8 high tensile bolts are often used for performance upgrades, such as installing aftermarket suspension parts or engine components. The manufacturing of M8 high tensile bolts requires precision to ensure proper fit and function. BOBFAST uses advanced CNC machining and threading equipment to produce M8 bolts with tight tolerances, accurate thread profiles, and consistent mechanical properties. Our M8 high tensile bolts also undergo a series of surface treatments, such as zinc plating or black oxide coating, to enhance corrosion resistance and extend the service life, making them suitable for both indoor and outdoor applications.
