Professional Applications & Engineering Value
These M10 hex head screws deliver critical engineering solutions where high tensile strength and reliable fastening are paramount. The Class 10.9 steel construction provides exceptional resistance to shear and tensile forces, making them ideal for heavy machinery, structural steel connections, and automotive assemblies. The partially threaded design concentrates strength where needed most while the coarse metric thread (1.5mm pitch) ensures rapid installation in time-sensitive production environments. With Rockwell C32 hardness, these external hex drive fasteners maintain integrity under repetitive stress cycles, reducing maintenance downtime in industrial equipment and construction applications where vibration resistance is critical.
Specification Summary & Compliance
Manufactured to ISO 4014 DIN 931 specifications with Class 6g thread fit tolerance ensuring precise dimensional accuracy. The 45mm length with 26mm minimum thread length provides optimal engagement depth. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations guarantees environmentally responsible manufacturing standards for global industrial applications.
