Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M7 hex head screws combine Class 8.8 strength with zinc plating to solve critical fastening challenges. The steel construction and fully threaded metric coarse design provide exceptional vibration resistance in machinery, automotive assemblies, and structural applications where loosening under dynamic loads is a concern. With 110,000 psi tensile strength and Rockwell C21 hardness, these fasteners maintain integrity under extreme pressure while the external hex drive ensures secure installation in confined spaces. Ideal for production lines requiring consistent performance, they prevent costly downtime and maintenance in heavy-duty industrial applications.
Specification Summary & Compliance
Manufactured to ISO 4017 specifications (equivalent to DIN 933) with Class 6h thread fit ensuring precise dimensional accuracy. These metric coarse thread screws feature M7 x 1 mm threading with right-hand direction and 16 mm length. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, making them suitable for global industrial applications requiring strict chemical substance control.
