Professional Applications & Engineering Value
These M30 hex head screws deliver critical performance in heavy machinery, structural steel connections, and industrial equipment where vibration resistance and permanent fastening are paramount. The Class 10.9 steel construction provides exceptional yield strength that prevents joint failure under dynamic loads, while the fully threaded design ensures uniform stress distribution across the entire 100mm length. The coarse metric thread with 3.5mm pitch maintains holding power in softer materials and allows for quicker installation compared to fine-thread alternatives. Engineered to ISO 4017 DIN 933 specifications, these external hex drive fasteners offer reliable torque transmission for high-tension applications in construction, manufacturing, and infrastructure projects.
Specification Summary & Compliance
Manufactured to ISO 4017 DIN 933 standards with Class 6g thread fit tolerance ensuring precise dimensional accuracy. The metric coarse threading (M30x3.5mm) with right-hand direction provides industry-standard compatibility. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations guarantees restricted substance-free components for global industrial use.
