Professional Applications & Engineering Value
These M30 socket head cap screws are engineered to address critical challenges in heavy machinery, automotive, and construction applications where vibration and dynamic loads are common. The black-oxide alloy steel construction combined with Class 12.9 strength provides exceptional resistance to fatigue and shock, preventing loosening and structural compromises. The coarse thread (M30x3.5mm) ensures quick assembly and reliable holding power in brittle materials or where frequent disassembly is required. With a fully threaded metric design and precise hex drive, these screws simplify maintenance and reduce downtime in industrial settings, making them ideal for demanding socket head applications that require both durability and ease of use.
Specification Summary & Compliance
This socket head cap screw features M30x3.5mm coarse threads with a Class 5g6g thread fit per ISO metric standards, ensuring precise dimensional tolerance. Manufactured to DIN 912/ISO 4762 specifications, it guarantees consistent quality and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, meeting environmental and safety requirements for industrial use.
