Professional Applications & Engineering Value
This Class 10.9 hex head screw delivers critical engineering solutions where high tensile strength and reliable fastening are paramount. The M14x2mm coarse thread configuration ensures rapid assembly in heavy machinery, structural steel connections, and industrial equipment where vibration resistance is essential. The partially threaded design provides unthreaded shank sections for precise shear plane positioning, while the external hex drive accommodates high torque applications. Manufactured from hardened steel with Rockwell C32 hardness, these metric screws maintain integrity in demanding environments including construction, automotive assemblies, and manufacturing infrastructure where DIN 931 compliance guarantees interchangeability and dimensional accuracy across international projects.
Specification Summary & Compliance
This hex head screw features M14x2mm metric coarse threads with Class 6g tolerance, 85mm total length, and 34mm minimum thread length. Manufactured to DIN 931 specifications with Class 10.9 strength rating (150,000 psi tensile strength). Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications.
