Professional Applications & Engineering Value
This M12 hex head screw is engineered to solve critical challenges in industrial assembly, where vibration resistance and long-term reliability are paramount. The black-oxide steel finish offers excellent protection against rust and wear, extending service life in harsh conditions. Its serrated locking flange eliminates the need for additional washers or locknuts by biting into surfaces to prevent rotation, making it ideal for machinery, automotive frames, and structural applications. The coarse metric thread with a 1.75mm pitch ensures quick installation and robust performance in metals and composites, while the fully threaded design distributes stress evenly to reduce the risk of joint failure. Built to meet rigorous standards, this screw delivers consistent engineering value in high-stress environments.
Specification Summary & Compliance
This product features a Class 6g thread fit per metric standards, ensuring dimensional accuracy and interchangeability. It adheres to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming it is free from hazardous substances. Manufactured with a Rockwell C27 hardness and 130,000 psi tensile strength, it meets industrial requirements for durability and load-bearing capacity. The external hex drive and flanged design align with common assembly practices, providing reliable fastening solutions for professional use.
