Professional Applications & Engineering Value
Engineered for demanding industrial applications, these M30 hex head screws combine hot-dipped galvanized steel construction with Class 10.9 strength rating to solve critical fastening challenges. The partial threading design provides optimal clamp force distribution while the external hex drive enables high-torque installation in structural steel connections, heavy machinery assembly, and construction frameworks. The coarse metric thread (3.5 mm pitch) resists loosening under vibration, making these industrial fasteners ideal for bridge construction, mining equipment, and transportation infrastructure where corrosion resistance and 150,000 psi tensile strength are essential for long-term structural integrity.
Specification Summary & Compliance
Manufactured to DIN 6914/ISO 7412 standards with Class 6g thread tolerance for precision fit. Features M30x3.5 coarse thread configuration with 42 mm thread length and 200 mm total length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The hot-dipped galvanized surface treatment provides superior corrosion protection while maintaining Rockwell C32 hardness and Class 10.9 mechanical properties.
