- Compliance with ISO 4014, DIN 931, and ISO 898 standards guarantees consistent quality and interchangeability for global engineering projects.
Professional Applications & Engineering Value
This M14 hex head screw is engineered to address critical fastening challenges in industrial machinery, construction frameworks, and heavy equipment assembly. The Class 8.8 steel construction delivers high tensile strength and fatigue resistance, preventing joint loosening under dynamic loads. Its zinc-plated finish combats rust and corrosion in humid or outdoor settings, reducing downtime. The coarse metric thread (2 mm pitch) ensures quick engagement and reliable holding power in steel, aluminum, or composite materials. With a partially threaded design, it provides unthreaded shank support for shear-loaded connections, enhancing structural integrity in bolted joints and machinery mounts while meeting stringent ISO 4014 and DIN 931 specifications.
Specification Summary & Compliance
This fastener features M14 x 2 mm coarse threads with Class 6h thread fit for precise tolerance, ensuring smooth assembly. It adheres to ISO 4014, DIN 931, and ISO 898 manufacturing standards, confirming dimensional accuracy and mechanical properties. Regulatory compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006), guaranteeing environmental safety and material restrictions adherence.
