- Optimized torque transmission via 2.5mm hex drive, preventing stripping and enabling secure installation
- Precision metric coarse threading (M4 x 0.7mm) with Class 6g fit for quick assembly and vibration resistance
- Full threading along 22mm length provides maximum grip and uniform load distribution
- Standard 90° countersink angle allows for flush mounting in DIN 7991/ISO 10642 compliant applications
- Compliance with RoHS 3 and REACH guarantees environmental safety and regulatory adherence
Professional Applications & Engineering Value
These M4 flat head screws are engineered to address critical challenges in machinery, automotive, and structural assemblies where high-strength fastening and corrosion resistance are paramount. The black-oxide alloy steel construction, combined with a Rockwell C32 hardness, ensures durability against wear and environmental exposure. The fully threaded design and coarse metric thread (0.7mm pitch) facilitate rapid installation in metals and composites, reducing assembly time while maintaining Class 10.9 tensile strength. Ideal for applications requiring flush surfaces, the flat head with standard profile and 90° countersink angle conforms to DIN 7991/ISO 10642 specifications, ensuring compatibility with standardized components and enhancing engineering reliability.
Specification Summary & Compliance
This fastener adheres to Class 6g thread fit for precise dimensional accuracy and features a fully threaded M4 x 0.7mm coarse thread in a right-hand direction. Manufactured to meet DIN 7991 and ISO 10642 standards, it ensures consistent performance in metric-based systems. Compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations confirms the absence of hazardous substances, supporting sustainable industrial practices.
