Professional Applications & Engineering Value
This M12 hex head screw is engineered to address critical challenges in industrial settings, where vibration, heavy loads, and harsh conditions can compromise fastener integrity. The Class 10.9 steel construction, combined with a metric coarse thread and 1.75mm pitch, delivers robust clamping force and resistance to loosening, making it ideal for machinery, structural frameworks, and automotive assemblies. The partially threaded design concentrates strength where needed, while the external hex drive facilitates quick installation with standard tools. By meeting DIN 931 standards and featuring a black finish, it ensures reliable performance in applications requiring high tensile strength and corrosion resistance, ultimately reducing maintenance costs and downtime.
Specification Summary & Compliance
This fastener adheres to precise dimensional tolerances, including a Class 6g thread fit per ISO standards, and is manufactured in compliance with DIN 931 specifications. It meets regulatory requirements such as RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), ensuring environmental safety and suitability for global industrial use.
