• Superior load-bearing capacity with 150,000 psi tensile strength and Class 10.9 grade, preventing fastener failure under extreme stress
• Optimized thread engagement through Class 6g thread fit and coarse 2 mm pitch, enabling faster installation and reduced cross-threading risks
• Enhanced torque transmission via external hex drive and 27 mm head width, allowing secure tightening with standard tools
• Partial threading design providing 28 mm threaded length and 52 mm grip length, ideal for applications requiring precise clamp load distribution
• High durability backed by Rockwell C32 hardness, maintaining structural integrity through repeated load cycles
• Global compliance assurance meeting DIN 6914/ISO 7412 specifications plus RoHS 3 and REACH regulations

Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these M16 hex head screws solve critical fastening challenges in structural steel connections, machinery assembly, and construction frameworks. The hot-dipped galvanized steel construction provides a sacrificial zinc barrier that actively resists rust and chemical corrosion, significantly extending service life in outdoor or high-moisture environments. With Class 10.9 strength grade and 150,000 psi tensile strength, these metric coarse thread fasteners maintain joint integrity under dynamic loads and vibration, preventing catastrophic failures in critical infrastructure. The partially threaded design concentrates clamping force precisely where needed, while the external hex drive ensures compatibility with standard industrial torque tools for efficient installation across manufacturing, bridge construction, and heavy equipment maintenance applications.

Specification Summary & Compliance

These M16 x 2 mm hex head screws feature Class 6g thread tolerance for precision fit and are manufactured to DIN 6914/ISO 7412 dimensional and mechanical specifications. The 80 mm overall length with 28 mm threaded portion and 52 mm grip length ensures proper engagement in standard applications. Compliance is verified with RoHS 3 (2015/863/EU) for restricted substance control and REACH (EC 1907/2006) for chemical safety, making them suitable for regulated industrial markets across international jurisdictions.
