Professional Applications & Engineering Value

These M18 hex head screws deliver critical performance advantages in industrial machinery, structural frameworks, and heavy equipment assemblies. The 18-8 Stainless Steel composition provides inherent resistance to oxidation and chemical exposure, eliminating corrosion-related failures in manufacturing plants, marine environments, and outdoor installations. The coarse 2.5mm pitch metric threading ensures rapid installation and superior vibration resistance compared to fine-thread alternatives, while the external hex drive accommodates high torque applications without cam-out issues. With full threading along the entire 70mm shaft length, these fasteners maintain consistent clamping force across varying material thicknesses, making them ideal for structural steel connections, conveyor systems, and heavy-duty fabrication projects where reliability cannot be compromised.

Specification Summary & Compliance

This fully threaded hex head screw features M18 x 2.5mm coarse threads with Class 6g tolerance per ISO metric standards, ensuring precise thread engagement. Manufacturing conforms to DIN 933 specifications for dimensional accuracy, including 27mm hex head width and 11.5mm head height. The fastener is RoHS 3 (2015/863/EU) compliant and meets REACH (EC 1907/2006) requirements regarding substance restrictions, making it suitable for regulated industrial markets and international procurement specifications.
