Professional Applications & Engineering Value
These M8 flanged hex button head screws deliver exceptional engineering value in industrial machinery, automotive assemblies, and heavy equipment applications. The zinc-plated alloy steel construction provides reliable corrosion protection while maintaining the Class 10.9 strength rating required for high-stress connections. The wide flange design eliminates the need for separate washers, distributing clamp load effectively and preventing surface damage to softer materials. With fully threaded coarse pitch (M8x1.25mm) and 5mm hex drive, these metric fasteners ensure rapid installation and superior torque transmission, making them ideal for production lines where efficiency and reliability are paramount. The rounded button head profile offers a clean, low-profile finish while maintaining excellent drive engagement.
Specification Summary & Compliance
This flanged hex button head screw features precision M8x1.25mm coarse thread with Class 6h thread fit according to metric standards. Manufactured to ISO 7380-2 specifications with 20mm length and 17.8mm flange diameter. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors. The Class 10.9 strength classification and Rockwell C32 hardness guarantee consistent performance in demanding applications.
