Professional Applications & Engineering Value
Engineered for demanding industrial applications, these Class 10.9 hex head screws deliver critical performance where vibration resistance and structural integrity are paramount. The zinc-plated steel construction provides essential corrosion protection for machinery, automotive assemblies, and outdoor equipment exposed to moisture and chemicals. The integrated flange design eliminates the need for separate washers, reducing assembly time while providing superior load distribution on joint surfaces. With M6 coarse threading and full-thread engagement, these metric fasteners ensure rapid installation in production environments while maintaining the high tensile strength required for structural connections and heavy equipment manufacturing.
Specification Summary & Compliance
Manufactured to precise metric dimensions with M6 x 1 mm coarse thread and Class 6g thread fit tolerance ensuring consistent performance. Complies with JIS B 1189 Type 2 specifications for hex flange screws and meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards. The Class 10.9 strength rating and Rockwell C32 hardness guarantee mechanical properties suitable for high-stress applications requiring reliable industrial fastening solutions.
