• Streamlined, low-profile installation thanks to the standard flat head with 90° countersink, ideal for flush-mounting requirements.
• Robust Rockwell C22 hardness provides excellent wear resistance and maintains thread integrity through repeated use.
• Quick and easy assembly with fully threaded M5x0.8mm coarse thread design, enabling faster driving and secure holding power.
• Guaranteed dimensional precision with Class 6h thread fit, ensuring consistent performance and interchangeability.

Professional Applications & Engineering Value

This M5 flat head screw is engineered to solve critical fastening challenges in industrial machinery, automotive assemblies, and electronic enclosures. The zinc-plated alloy steel construction provides a durable barrier against rust and corrosion, significantly reducing maintenance needs in harsh operating conditions. The Torx T25 drive offers superior torque transfer compared to traditional drives, preventing strip-out and ensuring consistent clamp load in high-vibration environments. With its fully threaded coarse pitch design, it delivers rapid installation and excellent pull-out resistance in brittle materials or pre-tapped holes. The 90° countersink and flat head profile allow for a smooth, flush finish, making it ideal for applications where protruding fastener heads are not permissible, enhancing both safety and aesthetics.
