Professional Applications & Engineering Value
This M18 hex head screw delivers critical performance in industrial fastening where corrosion resistance and mechanical strength are paramount. The 18-8 Stainless Steel material prevents rust and degradation in humid or chemical-exposed settings, such as machinery, structural frameworks, and marine equipment. Its coarse metric thread and Class 6g thread fit ensure precise engagement and vibration resistance, reducing the risk of loosening under dynamic loads. The external hex drive facilitates high-torque installation, making it suitable for assembly lines and maintenance operations. With partial threading, the screw concentrates thread engagement where needed, optimizing clamp load and minimizing material usage. Engineers value its adherence to DIN 931 for consistent quality and compatibility in European and global projects.
Specification Summary & Compliance
This screw features a metric M18 x 2.5mm coarse thread with Class 6g thread fit per ISO standards, ensuring tight dimensional tolerances. It is manufactured in accordance with DIN 931 specifications for hex head bolts and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming it is free of hazardous substances and safe for industrial use.
