Professional Applications & Engineering Value
This M5 socket head cap screw is engineered to address critical challenges in demanding industrial settings, such as machinery assembly, automotive components, and heavy equipment. The black-oxide alloy steel construction provides enhanced corrosion protection, reducing maintenance needs in humid or chemically exposed environments. With a coarse thread (0.8 mm pitch) and Class 5g6g thread fit, it ensures rapid installation and reliable grip in metals and composites, minimizing the risk of loosening under dynamic loads. The partially threaded design allows for precise clamping without over-tightening, making it ideal for applications requiring exact alignment and high tensile strength. By meeting DIN 912/ISO 4762 standards, it delivers consistent quality for engineers and procurement specialists seeking durable, high-performance industrial fasteners.
Specification Summary & Compliance
This screw features a metric thread size M5 x 0.8 mm with Class 5g6g thread fit for precise dimensional accuracy. It adheres to DIN 912/ISO 4762 manufacturing specifications, ensuring uniformity and reliability. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets environmental and safety standards for global industrial use.
