Professional Applications & Engineering Value
These M18 hex head screws deliver critical engineering solutions for heavy machinery, structural steel connections, and industrial equipment assembly. The Class 10.9 steel composition provides the necessary tensile strength to withstand extreme mechanical stresses, while the partially threaded design concentrates clamping force precisely where needed. The metric coarse thread with 2.5mm pitch ensures rapid installation in time-sensitive production environments and maintains integrity under vibrational loads. With ISO 4014 compliance and external hex drive compatibility, these fasteners integrate seamlessly into existing industrial systems, reducing assembly time and minimizing the risk of joint failure in critical applications.
Specification Summary & Compliance
This 60mm length hex head screw features M18 x 2.5mm coarse threading with Class 6g thread fit tolerance for precision engagement. Manufactured to ISO 4014 specifications (equivalent to DIN 931) with partial threading extending 37mm minimum. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across industrial sectors.
