Professional Applications & Engineering Value
This M8 x 1.25mm Class 10.9 black-oxide alloy steel rounded head screw is engineered to address common industrial challenges such as corrosion, high-stress fatigue, and assembly efficiency. The black-oxide surface treatment enhances durability by resisting rust and wear in moist or chemically aggressive settings, while the alloy steel construction with Rockwell C32 hardness maintains structural integrity under dynamic loads. Featuring a fully threaded metric coarse pitch and right-hand thread direction, it ensures rapid installation and secure fastening in machinery, automotive assemblies, and structural frameworks. The integrated flange eliminates the need for separate washers, streamlining inventory and reducing installation time, making it a cost-effective solution for high-performance industrial applications.
Specification Summary & Compliance
This screw adheres to precise Class 6g thread fit and ISO 7380-2 standards for dimensional accuracy and interchangeability. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances. With a 25mm length, 17.8mm flange diameter, and fully threaded coarse spacing, it is manufactured to deliver reliable performance in demanding environments.
