Professional Applications & Engineering Value
These M16 hex head screws deliver critical engineering solutions for heavy-duty industrial applications where joint integrity is paramount. The Class 8.8 steel construction provides the necessary strength for structural connections, machinery assembly, and equipment manufacturing, while the zinc plating offers essential protection against environmental corrosion. The metric coarse threading with 2 mm pitch ensures rapid installation and superior resistance to vibrational loosening in dynamic load conditions. With fully threaded design and external hex drive, these fasteners maintain consistent clamping force across the entire engagement length, making them ideal for critical connections in construction, automotive, and industrial machinery where failure is not an option.
Specification Summary & Compliance
Manufactured to ISO 4017, DIN 933, and SAE J1199 specifications with Class 6h thread fit precision. The metric coarse thread (M16 x 2 mm) provides optimal engagement characteristics, while the 30 mm length and fully threaded configuration ensure maximum utility. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees safe usage across global markets, supported by Rockwell C21 hardness and 110,000 psi tensile strength verification.
