Professional Applications & Engineering Value

Engineered for heavy-duty industrial applications, these Class 10.9 metric hex screws deliver critical performance where vibration resistance and structural integrity are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for machinery, equipment frames, and structural assemblies exposed to operational stresses. The M10 x 1.5mm coarse thread with Class 6g fit ensures rapid installation while maintaining precise tolerance control, reducing assembly time in production environments. The rounded button head design offers a low-profile solution that clears obstructions while the 6mm hex drive accommodates high-torque applications without stripping. These fully threaded screws maintain consistent clamping force across the entire 16mm length, making them ideal for securing critical components in automotive, manufacturing, and construction applications where joint reliability cannot be compromised.

Specification Summary & Compliance
