Professional Applications & Engineering Value
Engineered for industrial machinery and precision equipment assembly, these M4 flat head screws deliver critical performance advantages where space constraints and material integrity are paramount. The black-oxide alloy steel construction provides essential corrosion protection in manufacturing environments while maintaining Rockwell C32 hardness for wear resistance. The fully threaded design with coarse 0.7mm pitch ensures maximum thread engagement in both metals and engineered plastics, preventing loosening under vibration. The 2.5mm hex drive configuration allows for high-torque installation in confined spaces, making these metric screws ideal for automotive components, industrial controls, and heavy-duty equipment where Class 10.9 strength is required.
Specification Summary & Compliance
This flat head screw maintains precision Class 6g thread fit according to metric standards with 14mm length and M4 x 0.7mm thread specifications. Manufacturing conforms to DIN 7991/ISO 10642 dimensional and performance requirements. The fastener demonstrates full compliance with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring suitability for global industrial supply chains.
