Professional Applications & Engineering Value
This M12 hex head screw delivers exceptional engineering value in demanding industrial applications where vibration resistance and corrosion protection are critical. The Class 8.8 steel construction combined with zinc plating provides reliable performance in machinery assembly, structural frameworks, and automotive components. The extra fine metric thread with 1.25mm pitch ensures superior clamping force distribution, making it ideal for applications requiring precise tension control and resistance to loosening under dynamic loads. The partially threaded design offers optimal strength in the unthreaded portion while maintaining secure fastening in the threaded section, solving common challenges of thread stripping and fatigue failure in high-stress environments.
Specification Summary & Compliance
This fastener meets ISO 8765 and DIN 960 specifications with Class 6h thread fit precision and Class 8.8 strength grade. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial sectors. The metric thread system features M12 x 1.25mm extra fine pitch with right-hand threading and 30mm minimum thread length on an 80mm overall length screw.
