- Superior corrosion resistance provided by zinc-plated alloy steel construction, extending service life in harsh environments
- Optimized torque transmission through 5mm hex drive design, ensuring secure installation and preventing tool slippage
- Precision thread engagement with Class 6g fit and coarse 1.25mm pitch, enabling faster assembly and reduced cross-threading risks
- Enhanced durability with Rockwell C32 hardness, maintaining structural integrity under repeated vibration and mechanical stress
- Full threading along 12mm length for maximum grip and uniform stress distribution across fastened components
- Compliant with international standards including ISO 7380, RoHS 3, and REACH, ensuring global regulatory acceptance
Professional Applications & Engineering Value
This M8 rounded head screw delivers critical engineering solutions where vibration resistance and structural reliability are paramount. The zinc-plated alloy steel construction provides essential corrosion protection for industrial equipment, machinery assemblies, and outdoor applications exposed to moisture and chemicals. With its Class 10.9 strength rating and fully threaded metric design, it maintains clamping force in high-vibration environments common in automotive subsystems, heavy equipment manufacturing, and structural steel connections. The button head profile offers a low-profile finish while the hex drive ensures precise torque application during installation, making it ideal for confined spaces where both aesthetic appeal and mechanical performance are required.
Specification Summary & Compliance
Manufactured to ISO 7380 specifications with Class 6g thread tolerance for precise fitment. The fastener maintains dimensional accuracy with M8 x 1.25mm coarse threading and 12mm length. Compliance certifications include RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) for environmental safety standards. The mechanical properties meet Class 10.9 requirements with documented tensile strength of 140,000 psi and Rockwell C32 hardness verification.
