Professional Applications & Engineering Value
Engineered for demanding industrial environments, these M12 hex head screws combine Class 8.8 high-tensile steel with zinc yellow-chromate plating to solve critical fastening challenges. The partially threaded design provides optimal clamping force distribution, while the integrated flange acts as a built-in washer, preventing surface damage and maintaining joint integrity. These metric coarse thread screws are particularly valuable in heavy machinery, structural steel connections, and equipment assembly where vibration resistance and corrosion protection are paramount. The external hex drive ensures maximum torque transmission during installation, making them ideal for high-stress applications requiring reliable, long-term fastening solutions.
Specification Summary & Compliance
Manufactured to exacting standards with Class 6g thread tolerance and 50mm length specification. Fully compliant with DIN 6921 dimensional requirements and ISO 898-1 mechanical property standards. The 16mm hex head and 26.6mm flange diameter ensure proper tool engagement and load distribution. Meets international regulatory requirements including RoHS and REACH environmental directives for industrial applications.
