Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M10 hex head screw delivers critical reliability where failure is not an option. The Class 10.9 steel construction provides exceptional tensile strength, resisting deformation under heavy loads in machinery, structural frameworks, and automotive assemblies. Its partially threaded design concentrates clamping force precisely where needed, preventing joint loosening from vibrations—a common challenge in dynamic environments. The metric coarse thread with 1.5mm pitch ensures rapid installation in brittle materials without stripping, while the external hex drive allows high-torque application with standard tools. This combination addresses key engineering pain points: maintaining integrity under stress, simplifying maintenance, and ensuring long-term performance in corrosive conditions, making it ideal for heavy equipment, construction, and manufacturing sectors.

Specification Summary & Compliance

This fastener adheres to DIN 931 specifications with precise Class 6g thread fit tolerance for consistent engagement. The M10 x 1.5mm coarse thread and 180mm length provide standardized dimensions compatible with metric systems. It fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and restricted substance control. Manufactured to meet Class 10.9 strength grade requirements, it guarantees reliable performance in regulated industrial applications.
