Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M30 hex head screws deliver critical performance where structural integrity matters most. The hot-dipped galvanized steel construction provides superior protection against corrosion in outdoor construction, bridgework, and marine environments. With Class 10.9 strength rating and 150,000 psi tensile strength, these metric coarse thread fasteners withstand extreme loads in steel frame assemblies, heavy machinery, and infrastructure projects. The partially threaded design ensures optimal stress distribution, while the external hex drive facilitates quick installation with standard tools, reducing assembly time in high-volume projects.
Specification Summary & Compliance
This M30x3.5 hex head screw features Class 6g thread fit per metric standards with 90mm total length and 40mm thread length. Manufactured to DIN 6914/ISO 7412 specifications with Class 10.9 strength classification and Rockwell C32 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use.
