Professional Applications & Engineering Value

These M16 hex head screws deliver critical engineering solutions where high tensile strength and corrosion protection are paramount. The Class 10.9 steel construction provides exceptional resistance to mechanical stress, making them ideal for structural steel connections, heavy machinery assembly, and industrial equipment manufacturing. The zinc yellow-chromate plating creates a robust barrier against oxidation and chemical exposure in outdoor or corrosive environments. With metric coarse threading (2mm pitch) and partial threading design, these fasteners offer optimal load distribution while preventing loosening under vibration. The external hex drive ensures straightforward installation with common tools, reducing assembly time in construction, automotive, and manufacturing applications where reliability cannot be compromised.

Specification Summary & Compliance

Manufactured to precise metric dimensions with 55mm length and 38mm minimum thread length. Features Class 6h thread fit tolerance for consistent engagement and M16x2mm coarse thread specification. Fully compliant with ISO 4014/DIN 931 international standards for dimensional accuracy and mechanical properties. The zinc yellow-chromate finish meets corrosion protection requirements while the Class 10.9 strength rating (150,000 PSI tensile strength, Rockwell C32 hardness) ensures performance consistency across industrial applications.
