- Optimized thread design with coarse M12 x 1.75mm pitch and Class 5g6g fit ensures quick assembly and reliable holding power.
- Partially threaded shank offers flexibility for applications requiring both clamped and unthreaded sections, improving joint integrity.
- Compliance with international standards including DIN 912/ISO 4762, RoHS 3, and REACH, guaranteeing quality and environmental safety.
Professional Applications & Engineering Value
This Class 12.9 socket head cap screw is engineered to address critical challenges in demanding industrial settings, such as machinery assembly, automotive systems, and heavy equipment manufacturing. The alloy steel construction with blue-dyed zinc plating not only enhances corrosion resistance but also provides visual identification for quality control. Its metric coarse thread (M12 x 1.75mm) and hex drive design facilitate rapid installation and disassembly, minimizing downtime in production lines. With a partially threaded rod and high tensile strength, it effectively distributes load stresses, preventing loosening in vibrating environments and ensuring long-term reliability for industrial fasteners in structural and mechanical applications.
Specification Summary & Compliance
This product adheres to precise dimensional tolerances with a Class 5g6g thread fit and complies with DIN 912/ISO 4762 standards for metric socket head cap screws. It meets regulatory requirements including RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring it is free from hazardous substances and suitable for global industrial use.
