Professional Applications & Engineering Value
This M4 flat head screw delivers critical engineering advantages for industrial assembly where space constraints and corrosion resistance are paramount. The blue-dyed zinc-plated alloy steel construction provides superior protection against environmental degradation while maintaining Rockwell C32 hardness for long-term reliability. The metric coarse threading (M4 x 0.7mm) with Class 6g tolerance ensures rapid installation and secure fastening in machinery, automotive components, and electrical enclosures. The flat head design with 90° countersink creates flush surfaces ideal for applications requiring aerodynamic profiles or smooth finishes. Engineered to DIN 7991/ISO 10642 standards, these hex drive screws offer consistent performance in high-vibration environments where fastener integrity is critical to operational safety.
Specification Summary & Compliance
Manufactured to precise metric dimensions with M4 x 0.7mm coarse threading meeting Class 6g thread fit tolerance. Fully compliant with DIN 7991/ISO 10642 manufacturing specifications. Meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The Class 10.9 strength rating ensures 120,000 psi tensile strength with Rockwell C32 hardness for heavy-duty applications.
