Professional Applications & Engineering Value
These M4 metric screws with black-oxide steel construction address critical industrial fastening challenges where corrosion resistance and consistent performance are paramount. The Torx T20 drive system provides superior torque transfer compared to traditional drive types, reducing installation time and preventing fastener damage in high-volume assembly operations. With Class 6g thread fit precision and fully threaded design, these fasteners deliver reliable clamping force in machinery, electrical enclosures, and automotive components where vibration resistance is essential. The combination of 60,000 PSI tensile strength and Rockwell B71 hardness ensures these screws maintain integrity under mechanical stress, while the coarse thread pitch facilitates quick installation in various materials including steel, aluminum, and engineered plastics.
Specification Summary & Compliance
These metric fasteners feature precise M4 x 0.7mm coarse thread with Class 6g thread fit tolerance according to ISO metric standards. The 12mm length provides optimal engagement for medium-duty applications. Manufacturing and quality control adhere to ISO 7045 dimensional specifications for pan head screws. Environmental compliance is verified through RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) certifications, ensuring these components meet current regulatory requirements for industrial use across global markets.
