Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M22 hex head screws deliver critical performance where structural integrity is paramount. The hot-dipped galvanized steel construction provides superior protection against corrosion in outdoor construction, bridge work, and marine environments. With 150,000 psi tensile strength and Class 10.9 rating, these partially threaded bolts effectively distribute clamping forces across the 76 mm grip length, preventing joint relaxation in vibrating machinery and structural steel connections. The coarse metric thread with 2.5 mm pitch ensures rapid installation in structural steel, heavy equipment assembly, and industrial machinery while maintaining vibration resistance throughout the fastener's service life.
Specification Summary & Compliance
This M22x2.5 hex head screw features precise Class 6g thread fit tolerance with 34 mm thread length and 110 mm overall length. Manufactured to DIN 6914/ISO 7412 specifications for structural bolting applications. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The external hex drive with 36 mm head width and 14 mm head height provides standardized installation compatibility with industry-standard tools.
