Professional Applications & Engineering Value
These M30 hex head screws deliver critical engineering advantages in demanding industrial settings where failure is not an option. The hot-dipped galvanized steel construction provides a thick, sacrificial zinc coating that protects against rust and corrosion in outdoor applications, chemical processing plants, and marine environments. The Class 10.9 strength rating combined with Rockwell C32 hardness ensures these metric coarse thread bolts maintain clamping force under extreme vibration and dynamic loads common in heavy machinery, structural steel connections, and infrastructure projects. The partial threading design with 42mm thread length and 78mm grip length creates an optimal unthreaded shank section for shear strength while allowing precise tension control in bolted joints requiring both alignment and clamping functions.
Specification Summary & Compliance
This hex head screw features M30x3.5 metric coarse threads with Class 6g thread fit tolerance for precise engagement. Manufacturing strictly follows DIN 6914/ISO 7412 specifications ensuring dimensional accuracy and performance reliability. The fastener is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making it suitable for regulated industries and international projects requiring certified components.
