Professional Applications & Engineering Value
This M16 hex head screw is engineered to address critical challenges in industrial assembly and heavy machinery. The Class 8.8 steel construction, combined with a Rockwell C21 hardness, provides exceptional resistance to shear forces and fatigue, preventing joint failure under dynamic loads. The coarse metric thread (2mm pitch) ensures rapid installation and superior performance in materials where fine threads might strip, while the fully threaded 35mm length offers versatile clamping across varying material thicknesses. The external hex drive design allows for high torque application with standard tools, making it ideal for structural steelwork, industrial equipment manufacturing, and automotive applications where high-strength fastening and reliability are non-negotiable.
Specification Summary & Compliance
This metric hex head screw features an M16 x 2mm coarse thread with a Class 6g thread fit tolerance, ensuring precision and compatibility. It is manufactured in accordance with the ISO 4017 / DIN 933 standard, confirming dimensional consistency and mechanical properties. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, affirming its suitability for use in environmentally conscious and regulated industrial markets.
