Professional Applications & Engineering Value
This M16 hex head screw delivers critical engineering solutions for heavy-duty industrial applications where high tensile strength and reliable fastening are paramount. The Class 10.9 steel construction with Rockwell C32 hardness provides exceptional resistance to vibration loosening and structural fatigue, making it ideal for construction machinery, structural steel connections, and industrial equipment assembly. The partially threaded design allows unthreaded shank sections to bear shear loads directly, while the coarse metric threading ensures rapid installation in various materials. Compliant with DIN 931 standards, these hex head fasteners offer predictable performance in demanding environments where failure is not an option.
Specification Summary & Compliance
This metric hex head screw features M16 x 2mm coarse threading with Class 6g thread tolerance for precision fit. The 240mm length with 38mm minimum thread length provides versatile application coverage. Manufactured to DIN 931 specifications with Class 10.9 strength rating, 150,000 psi tensile strength, and Rockwell C32 hardness. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for responsible industrial use.
