These 8.8 grade high-strength fasteners comply with GB824 standard, featuring a **low thin head** and torx (flower-shaped) internal hex drive. Made of high-quality carbon steel, they possess high hardness, superior tensile strength and stable mechanical properties for heavy-duty fastening. The torx socket design effectively prevents slipping during installation, while the low-profile cylindrical head fits limited mounting spaces. Precise thread processing ensures firm connection and excellent anti-loosening performance under vibration. Widely used in mechanical equipment, automotive parts, electrical appliances, precision instruments and industrial assembly. Each screw is strictly inspected for dimensional accuracy and mechanical performance. Available in full specifications with factory-direct supply, providing reliable high-strength fastening solutions for industrial and mechanical applications.
