Professional Applications & Engineering Value

Engineered for demanding industrial applications, these M14 hex head screws deliver critical performance advantages through their Class 10.9 high-tensile steel construction and zinc yellow-chromate plating. The combination of 150,000 psi tensile strength and Rockwell C32 hardness ensures reliable fastening in heavy machinery, structural steel connections, and automotive assemblies where vibration resistance and load-bearing capacity are paramount. The coarse thread pitch (2mm) provides superior grip in both metallic and composite materials, while the external hex drive design allows for high-torque installation without stripping. Meeting ISO 4017/DIN 933 specifications, these fully threaded fasteners eliminate the need for multiple component types, streamlining inventory and reducing assembly time in manufacturing and construction projects.

Specification Summary & Compliance

This metric hex head screw features precise M14x2mm coarse threading with Class 6h thread fit tolerance, ensuring consistent engagement across applications. Manufactured to ISO 4017 (equivalent to DIN 933) standards for dimensional accuracy and mechanical properties. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations concerning chemical safety. With 30mm length and fully threaded design, it maintains the specified Class 10.9 strength grade throughout the entire shank for uniform load distribution.
