Professional Applications & Engineering Value
This M5 flat head screw is engineered from black-oxide alloy steel to address critical challenges in industrial assembly, such as vibration loosening and corrosion. The fully threaded coarse pitch design ensures maximum grip and distribution of load, reducing the risk of joint failure in machinery, automotive components, and structural frameworks. The hex drive enables efficient installation in confined spaces, while the 90° countersink angle provides a seamless fit, preventing protrusions that could interfere with moving parts. Ideal for applications requiring high-strength fastening with Class 10.9 performance, it delivers long-term reliability and minimizes maintenance needs in demanding environments.
Specification Summary & Compliance
This fastener features precise metric dimensions including M5 thread size with 0.8mm coarse pitch and Class 6g thread fit for consistent engagement. It adheres to DIN 7991/ISO 10642 standards, ensuring dimensional accuracy and performance reliability. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms its environmental safety and suitability for global industrial use.
