Professional Applications & Engineering Value
This M16 hex head screw is engineered to address critical challenges in heavy-duty industrial applications, such as construction, machinery assembly, and infrastructure projects. Made from Class 8.8 steel with a Rockwell C21 hardness, it withstands high stress and vibration, preventing loosening and fatigue failures. The zinc-plated finish combats corrosion in outdoor or humid conditions, while the coarse metric thread (2 mm pitch) ensures rapid installation and robust grip in coarse-grained materials. With a partially threaded shank and external hex drive, it provides precise clamping and easy tool access, making it a reliable choice for engineers seeking durable, high-performance fastening solutions that meet stringent international standards.
Specification Summary & Compliance
This fastener adheres to precise dimensional tolerances, including a Class 6h thread fit for consistent engagement and ISO 4014/DIN 931 specifications for metric hex head screws. It is manufactured to meet Class 8.8 strength grade requirements, ensuring high tensile and yield strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it is free from hazardous substances, supporting safe and sustainable industrial use.
