Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, this M24 hex head screw addresses critical challenges in machinery assembly, structural frameworks, and equipment manufacturing. The Class 8.8 strength grade steel and zinc plating work synergistically to combat corrosion and mechanical stress, preventing premature failures in harsh conditions. With a coarse metric thread (3mm pitch) and external hex drive, it ensures rapid, tool-friendly installation while maintaining high clamp force. Ideal for construction, automotive, and manufacturing sectors, this partially threaded bolt provides consistent performance where vibration resistance and load distribution are paramount, supported by its 110,000 psi tensile strength and precise thread fit (Class 6h).
Specification Summary & Compliance
This hex head screw adheres to tight dimensional tolerances, including a thread fit of Class 6h per ISO standards, ensuring compatibility with metric nuts and components. It meets ISO 4014, DIN 931, and SAE J1199 specifications for consistent quality and performance. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its safety and environmental suitability for global industrial use.
