Professional Applications & Engineering Value
This M18 socket head cap screw is engineered to address critical challenges in heavy-duty machinery, automotive assemblies, and structural frameworks. The Class 12.9 alloy steel construction, combined with a coarse metric thread (2.5mm pitch), delivers robust clamping force and vibration resistance, preventing loosening in dynamic operations. The black-oxide surface treatment enhances corrosion protection, making it ideal for outdoor or humid conditions where oxidation can compromise integrity. With a partially threaded shank, it accommodates precise tension control in bolted joints, reducing stress concentration and improving fatigue life. Trust this fastener for applications demanding high tensile strength and long-term reliability, from industrial equipment to construction projects.
Specification Summary & Compliance
This product adheres to Class 5g6g thread fit tolerances per metric standards, ensuring dimensional accuracy for seamless integration. It conforms to DIN 912 and ISO 4762 specifications for socket head cap screws, guaranteeing consistent manufacturing quality. Additionally, it is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, supporting environmental safety and regulatory requirements in global supply chains.
