Key Features & Benefits at a Glance
- Exceptional tensile strength with 100,000 psi rating ensures reliable performance in demanding applications, reducing failure risks.
- Superior corrosion resistance from black-oxide alloy steel coating prolongs service life in harsh industrial environments.
- High hardness (Rockwell C32) provides excellent wear resistance, maintaining thread integrity under repeated use.
- Flanged design with wide rounded head distributes clamping force evenly, minimizing surface damage and improving joint stability.
- Coarse metric thread (M8 x 1.25mm) enables faster installation and secure fastening in various materials.
- Class 6g thread fit ensures precise, consistent engagement with nuts and tapped holes for vibration-resistant assemblies.
- 5mm hex drive allows for high-torque application with standard tools, speeding up maintenance and assembly processes.
Professional Applications & Engineering Value
Engineered for heavy-duty industrial applications, these Class 10.9 metric screws combine black-oxide alloy steel construction with a fully threaded design to address critical challenges like vibration loosening and corrosion. The flanged rounded head eliminates the need for separate washers, providing a larger bearing surface that prevents sinkage in soft materials and enhances load distribution. With coarse threading (M8 x 1.25mm pitch), they offer quick installation in structural frameworks, machinery, and automotive assemblies, while the hex drive ensures secure tool engagement for high-torque requirements. Ideal for environments demanding high-strength fasteners with consistent performance under stress.
Specification Summary & Compliance
This M8 x 1.25mm screw features Class 6g thread fit per metric standards, ensuring dimensional accuracy and compatibility. It meets ISO 7380-2 specifications for rounded head hex screws and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming environmental safety and material restrictions adherence. The Class 10.9 strength grade and fully threaded design align with industrial quality benchmarks for reliable, repeatable use.
