Professional Applications & Engineering Value
This Class 12.9 socket head cap screw is engineered from black-oxide alloy steel to address critical challenges in demanding industrial settings. Its high tensile strength and hardness prevent failure in high-stress applications like heavy machinery, automotive assemblies, and precision equipment. The fully threaded metric coarse thread (M3.5 x 0.6 mm) ensures strong clamping force and resistance to loosening under vibration, while the hex drive allows for efficient installation in confined spaces. By meeting DIN 912 and ISO 4762 specifications, it guarantees dimensional accuracy and reliability, reducing downtime and maintenance costs in engineering projects.
Specification Summary & Compliance
This product features precise Class 6g thread fit and metric coarse threading (M3.5 x 0.6 mm) for consistent performance. It complies with DIN 912, ISO 4762, and ASTM A574M manufacturing standards, ensuring high-quality dimensions and mechanical properties. Additionally, it is RoHS 3 (2015/863/EU) compliant, adhering to environmental regulations for safe use in various industries.
