Professional Applications & Engineering Value
This M18 hex head screw is engineered to solve critical fastening challenges in industrial machinery, structural frameworks, and heavy-duty equipment assembly. Manufactured from 18-8 Stainless Steel, it provides excellent resistance to rust and oxidation, significantly extending service life in humid or corrosive environments. The coarse metric thread (2.5mm pitch) and Class 6g thread fit ensure quick, secure engagement with mating components, reducing assembly time and preventing thread stripping. The partially threaded design concentrates clamping force where it's needed most, preventing joint loosening under vibration. Its external hex drive facilitates high-torque installation, making it a reliable choice for maintenance and production lines requiring durable, corrosion-resistant fasteners.
Specification Summary & Compliance
This screw features an M18 x 2.5mm coarse thread with a Class 6g thread fit per ISO metric standards, ensuring precise dimensional tolerances. It is manufactured to meet DIN 931 specifications for hex head bolts. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming its safety for use in various industrial applications without hazardous substances.
