Professional Applications & Engineering Value

This M12 socket head cap screw is engineered from black-oxide alloy steel to address common industrial challenges like vibration-induced loosening and corrosion. The serrated locking flange provides a secure fit that resists back-off in machinery, automotive, and heavy equipment applications, while the metric coarse thread (1.75 mm pitch) ensures quick assembly and disassembly. With a partially threaded design, it concentrates strength where needed, reducing weight without compromising integrity. Ideal for precision engineering tasks, this fastener delivers consistent performance in high-torque environments, enhancing overall equipment reliability and reducing maintenance downtime.

Specification Summary & Compliance

This product adheres to metric coarse thread standards with a Class 5g6g thread fit for precise dimensional accuracy. It meets manufacturing specifications including a flange diameter of 22.5 mm and minimum thread length of 36 mm. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring no hazardous substances are used, making it suitable for global industrial and engineering applications requiring strict environmental and safety standards.
