- Compliance with RoHS 3 and REACH regulations ensures environmental safety and global market acceptability.
Professional Applications & Engineering Value
Engineered for precision assembly, this M4 socket head cap screw addresses common industrial challenges such as space constraints and vibration-induced loosening. The ultra-low profile head and coarse thread pitch (0.7mm) facilitate quick installation in compact machinery, automotive components, and electronic enclosures. Made from black-oxide alloy steel, it resists corrosion in humid or chemically exposed settings, while the Class 5g6g thread fit ensures tight tolerances for secure connections. Ideal for high-strength metric fastening in robotics, aerospace, and automation systems, it enhances reliability and reduces maintenance needs.
Specification Summary & Compliance
This screw adheres to metric thread standards with a Class 5g6g thread fit for precise dimensional accuracy. Length tolerance is controlled within -0.127mm to 0.127mm, ensuring consistency. Manufactured in compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, it meets stringent environmental and safety requirements for industrial use.
