Professional Applications & Engineering Value
This M16 hex head screw delivers exceptional engineering value in demanding industrial applications where reliability is paramount. The Class 10.9 strength grade combined with 150,000 PSI tensile strength makes it ideal for heavy machinery, structural steel connections, and automotive assemblies requiring sustained load-bearing capacity. The zinc yellow-chromate plating provides superior corrosion protection, significantly extending service life in outdoor or chemically aggressive environments. Precision metric fine threading with Class 6h fit ensures vibration resistance and prevents loosening in dynamic applications. The external hex drive facilitates high-torque installation without stripping, while the fully threaded design allows for maximum engagement depth in varied material thicknesses.
Specification Summary & Compliance
This metric hex head screw features M16x1.5mm fine threading with Class 6h thread fit tolerance for precision fastening. Manufactured from high-strength steel with Rockwell C32 hardness and dimensions of 70mm length, 24mm head width, and 10mm head height. The product complies with ISO 8676 DIN 961 standards and meets RoHS and REACH environmental directives. The zinc yellow-chromate plating provides corrosion resistance while maintaining dimensional accuracy per international fastener specifications.
