Professional Applications & Engineering Value
This M14x2 Class 10.9 hex head screw delivers exceptional engineering value through its high-strength steel construction and DIN 931 compliant design. The partially threaded configuration with 38mm minimum thread length provides optimal stress distribution, preventing thread stripping in soft materials while maintaining clamping force in structural assemblies. The coarse thread pitch ensures rapid installation and superior resistance to vibration loosening in heavy machinery, construction equipment, and automotive applications. With external hex drive compatibility, maintenance teams can achieve proper torque values using standard tools, reducing installation time and ensuring consistent joint integrity across industrial fastening operations.
Specification Summary & Compliance
This metric hex head screw features Class 6g thread fit tolerance and complies with DIN 931 manufacturing standards for dimensional precision. The fastener meets RoHS 3 (2015/863/EU) compliance and REACH (EC 1907/2006) certification requirements, ensuring environmental regulation adherence. Manufacturing specifications include right-hand thread direction, M14x2 coarse thread spacing, and 140mm overall length with partial threading for controlled engagement depth in industrial applications.
