- Exceptional mechanical strength from alloy steel, supporting up to 180,000 psi tensile strength for heavy-duty applications.
- High hardness rating of Rockwell C38 ensures excellent wear resistance and durability under repetitive stress.
- Flanged design eliminates the need for separate washers, providing a larger bearing surface and simplifying assembly.
- Precise Class 4h thread fit offers consistent engagement and reliable fastening in metric coarse thread assemblies.
- External 12-point drive with 12mm size allows for high-torque installation using standard tools, reducing slippage risks.
- Fully threaded shank ensures maximum grip and load distribution along the entire length for secure connections.
Professional Applications & Engineering Value
This M10 12-point flange screw is engineered to address critical challenges in heavy machinery, automotive, and construction sectors where vibration resistance and structural integrity are paramount. The black-oxide alloy steel construction combats rust and oxidation, making it ideal for outdoor or humid conditions. Its flanged feature distributes clamping force evenly, preventing surface damage and loosening under dynamic loads. With a coarse metric thread (M10x1.5) and Class 4h fit, it ensures quick assembly and reliable performance in high-stress environments, reducing maintenance downtime and enhancing operational safety.
Specification Summary & Compliance
This screw adheres to metric coarse thread standards with precise Class 4h thread fit for consistent dimensional accuracy. It is manufactured from alloy steel with a hardness of Rockwell C38 and tensile strength of 180,000 psi, meeting industry requirements for heavy-duty fastening. The product complies with relevant material and safety regulations, including RoHS and REACH, ensuring environmental and user safety in industrial applications.
