Professional Applications & Engineering Value
Engineered for heavy structural connections in construction, machinery, and industrial frameworks, these M30 hex head screws address critical challenges in load distribution and environmental durability. The hot-dipped galvanized steel construction provides a robust barrier against moisture and chemical exposure, significantly extending service life in outdoor or corrosive settings. With Class 10.9 tensile strength and coarse metric threading, the fastener ensures secure, vibration-resistant joints in high-stress applications like steel framing, equipment mounting, and infrastructure projects. The partially threaded design concentrates clamping force where needed most, preventing joint loosening while maintaining alignment accuracy in industrial fastening systems.
Specification Summary & Compliance
This M30 x 3.5mm metric screw features Class 6g thread tolerance with right-hand coarse threading, 150mm total length, and 42mm threaded portion. Manufactured to DIN 6914/ISO 7412 specifications with full compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives. The Class 10.9 strength rating corresponds to 150,000 psi minimum tensile strength with Rockwell C32 hardness verification.
