Professional Applications & Engineering Value
This M4 brass coupling nut delivers exceptional engineering value through its corrosion-resistant properties and precision Class 6H metric threading. The combination of fully threaded coarse pitch design and external hex drive addresses critical industrial challenges by providing reliable, vibration-resistant connections in mechanical assemblies, electrical enclosures, and plumbing systems. The brass material inherently resists galvanic corrosion and maintains performance in temperature-variable environments, making it ideal for industrial machinery, automation equipment, and marine applications where metallic degradation compromises system integrity. The standardized metric coarse thread profile ensures quick assembly and disassembly while maintaining structural stability under dynamic loads.
Specification Summary & Compliance
This coupling nut features M4 coarse thread with Class 6H precision tolerance according to metric standards, ensuring exact thread engagement and reliable performance. The external hex drive measures 7mm across flats with a 12mm length, manufactured from high-quality brass for consistent mechanical properties. The product fully complies with REACH (EC 1907/2006) regulations and RoHS 3 (2015/863/EU) with exemption 6(c) for lead in copper alloys, meeting international environmental and safety standards for industrial components.
