Professional Applications & Engineering Value
This M18 hex head screw delivers exceptional engineering value across industrial sectors where reliability is paramount. Manufactured from Class 8.8 steel with zinc plating, it effectively combats corrosion in manufacturing plants, outdoor equipment, and structural assemblies. The coarse thread pitch (2.5mm) provides superior resistance to vibration-induced loosening, making it ideal for heavy machinery, automotive components, and construction applications. With full threading along its 60mm length, it ensures maximum engagement in thick materials and complex assemblies. The external hex drive design facilitates high-torque installation while the right-hand thread configuration aligns with standard industrial practices, streamlining maintenance and replacement procedures.
Specification Summary & Compliance
This hex head screw features precision Class 6h thread fit according to ISO 4017 specifications (equivalent to DIN 933), ensuring consistent dimensional accuracy and reliable performance. The fastener meets RoHS 3 (2015/863/EU) compliance for restricted substance control and REACH (EC 1907/2006) standards for chemical safety. Manufactured to deliver 110,000 psi tensile strength and Rockwell C21 hardness, this metric coarse thread screw maintains structural integrity across demanding industrial applications while adhering to international quality standards.
