- Corrosion-resistant black finish enhances longevity in demanding environments
Professional Applications & Engineering Value
This M18 hex head screw delivers critical engineering value in heavy-duty applications where failure is not an option. Manufactured from high-grade steel with a Class 10.9 strength rating, it provides the structural integrity needed for construction frameworks, industrial machinery, and infrastructure projects. The coarse metric thread (2.5mm pitch) ensures rapid assembly and superior resistance to vibration loosening, while the partially threaded design offers optimal clamping force distribution. The external hex drive accommodates high torque requirements, making it ideal for bolted connections in steel structures, equipment manufacturing, and automotive assemblies where ISO 4014 DIN 931 compliance is mandatory.
Specification Summary & Compliance
This fastener maintains Class 6g thread tolerance per metric standards with precise dimensional control. Manufacturing strictly adheres to ISO 4014 DIN 931 specifications for hex head screws, ensuring dimensional interchangeability and performance reliability. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming its suitability for environmentally conscious procurement and international industrial supply chains.
