Professional Applications & Engineering Value
These M20 hex head screws deliver critical performance in demanding industrial applications where corrosion resistance and mechanical strength are paramount. The 18-8 Stainless Steel composition provides excellent protection against rust and chemical exposure, making them ideal for marine equipment, food processing machinery, and outdoor structural assemblies. The coarse thread metric design with 2.5mm pitch ensures rapid installation and superior holding power in various materials, while the fully threaded configuration eliminates weak points and distributes stress evenly. The external hex drive with substantial 30mm head enables high-torque tightening without deformation, solving common installation challenges in heavy machinery, construction frameworks, and manufacturing equipment where vibration resistance and long-term reliability are essential.
Specification Summary & Compliance
Manufactured to ISO 4017 / DIN 933 specifications with Class 6g thread fit tolerance for precise dimensional accuracy. The metric coarse thread (M20 x 2.5mm) and 110mm length provide standardized compatibility across industrial systems. These screws maintain full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current substance restriction requirements for international industrial use.
