Key Features & Benefits at a Glance
- Exceptional tensile strength with Class 10.9 rating (120,000 psi) ensures reliable performance under high-stress industrial conditions.
- Corrosion-resistant zinc plating on alloy steel extends service life in harsh environments, reducing maintenance and replacement costs.
- Precision 6g thread fit and coarse M5 x 0.8mm threading provide secure, vibration-resistant fastening with easy installation.
- 90° countersink angle and flat head design allow for flush mounting, minimizing protrusion and enhancing safety in assembled components.
- Fully threaded shank offers consistent grip along the entire 30mm length, improving load distribution and joint integrity.
- Hex drive (3mm) enables efficient torque application with standard tools, speeding up assembly and disassembly processes.
- Compliance with DIN 7991, RoHS 3, and REACH guarantees adherence to international quality and environmental standards for global supply chain compatibility.
Professional Applications & Engineering Value
Engineered for demanding industrial applications, this M5 flat head screw combines zinc-plated alloy steel construction with a Class 10.9 strength grade to address common challenges like vibration loosening and corrosion in machinery, automotive, and structural assemblies. The fully threaded metric screw with coarse 0.8mm pitch ensures rapid installation and robust clamping force, while the 90° countersink angle facilitates seamless integration into pre-drilled surfaces. Ideal for use in equipment requiring high tensile strength and compliance with DIN 7991 specifications, it provides long-term reliability in environments exposed to dynamic loads and moisture, reducing downtime and enhancing operational safety.
Specification Summary & Compliance
This fastener features precise M5 x 0.8mm coarse threading with a Class 6g thread fit per ISO standards, ensuring dimensional accuracy and interchangeability. Manufactured to meet DIN 7991 specifications, it includes full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming the absence of hazardous substances. The 30mm length and Rockwell C32 hardness further validate its conformance to rigorous industrial requirements for strength and durability.
