Professional Applications & Engineering Value

This M14 hex head screw delivers critical engineering solutions for industrial assembly challenges where vibration resistance and structural integrity are paramount. The Class 8.8 steel construction with Rockwell C21 hardness provides the necessary strength for heavy machinery, structural frameworks, and equipment manufacturing. The zinc plated finish offers essential protection against corrosion in manufacturing facilities, outdoor installations, and high-humidity environments. The coarse thread metric design with 2mm pitch ensures rapid installation and superior holding power in steel-to-steel applications, while the partially threaded configuration concentrates clamping force where needed most. These external hex drive fasteners are particularly valuable in construction, automotive, and industrial maintenance where reliable, high-strength connections are non-negotiable.

Specification Summary & Compliance

This 130mm hex head screw features precise Class 6h thread fit tolerance per metric standards with M14 x 2mm coarse thread specifications. Manufacturing complies with ISO 4014 dimensional requirements, DIN 931 configuration standards, and ISO 898 mechanical property specifications. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility and workplace safety standards.
