Professional Applications & Engineering Value

These M30 hex head screws deliver critical engineering solutions where structural integrity cannot be compromised. The hot-dipped galvanized steel construction provides superior protection against corrosion in outdoor construction, bridgework, and marine applications. With Class 10.9 strength rating and Rockwell C32 hardness, these fasteners maintain clamping force under extreme vibration and dynamic loads common in heavy machinery and structural steel connections. The partially threaded design ensures precise load transfer while the external hex drive accommodates high-torque installation tools. Engineered to DIN 6914/ISO 7412 standards, these metric hex screws provide reliable performance in industrial bolting applications where failure is not an option.

Specification Summary & Compliance

Manufactured to precise metric dimensions with M30x3.5 coarse threads meeting Class 6g tolerance for optimal fit. The 75mm length includes 40mm thread length and 35mm grip length for controlled clamping. Compliant with DIN 6914/ISO 7412 specifications for structural applications. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across global industrial markets. The Class 10.9 strength classification corresponds to 150,000 PSI tensile strength with Rockwell C32 hardness for consistent performance.
