Professional Applications & Engineering Value
This M20 hex head screw delivers critical engineering solutions for heavy-duty industrial applications where vibration resistance and structural integrity are paramount. The extra fine 1.5mm thread pitch provides superior holding power in machinery, equipment assembly, and structural frameworks, preventing loosening under dynamic loads. The Class 8.8 strength rating (110,000 psi tensile strength) combined with Rockwell C21 hardness ensures reliable performance in high-stress environments. The zinc plated finish offers essential corrosion protection for extended service life in manufacturing facilities, construction sites, and outdoor installations. The partially threaded design allows for precise clamping force distribution, making it ideal for applications requiring controlled tension and secure fastening in automotive, machinery, and industrial equipment assembly.
Specification Summary & Compliance
Manufactured to ISO 8765 DIN 960 standards with Class 6h thread fit precision and extra fine 1.5mm pitch threading. Features M20 metric thread size, 100mm length with 46mm minimum thread length, and right-hand thread direction. The steel construction with zinc plating meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements for environmental safety and regulatory adherence in industrial applications.
