Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these M16 hex head screws deliver critical performance where structural integrity matters most. The Class 8.8 steel construction provides optimal strength-to-weight ratio, resisting deformation under high tensile loads common in machinery assembly, structural steel connections, and equipment manufacturing. The coarse thread pitch (2mm) enables rapid installation in both metallic and composite materials, while the fully threaded design ensures maximum clamping force distribution. With external hex drive and standardized ISO 4017 dimensions, these fasteners integrate seamlessly into existing tooling systems, reducing installation time and minimizing assembly errors in production environments.
Specification Summary & Compliance
This metric hex head screw features M16x2mm coarse threads with Class 6g thread tolerance per ISO standards. Manufacturing complies with ISO 4017 (equivalent to DIN 933) dimensional requirements. The fastener meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance for environmental safety. With 50mm length and right-hand thread direction, it maintains consistent performance across industrial applications requiring high tensile strength and reliable threading.
