Professional Applications & Engineering Value

These M18 hex head screws deliver critical engineering solutions for heavy-duty industrial applications where fastener failure is not an option. The Class 10.9 steel construction provides exceptional resistance to vibration loosening and dynamic loads, making them ideal for machinery assembly, structural steel connections, and automotive components. The metric coarse thread with Class 6g tolerance ensures reliable engagement in both through-holes and tapped applications, while the fully threaded design offers versatile positioning options. The external hex drive accommodates standard tools for efficient installation in confined spaces, significantly reducing assembly time in production environments. These DIN 933 compliant fasteners represent the gold standard for high-strength bolting applications across manufacturing, construction, and equipment maintenance sectors.

Specification Summary & Compliance
