Professional Applications & Engineering Value

Engineered for demanding industrial applications, this M12 coupling nut solves critical connection challenges where corrosion resistance and thread reliability are paramount. The 18-8 stainless steel material provides excellent protection against chemical exposure and atmospheric corrosion, making it ideal for marine equipment, food processing machinery, and outdoor structural assemblies. The fully threaded design and Class 6H precision threads ensure uniform stress distribution across the entire 30mm length, preventing thread stripping and maintaining connection integrity under dynamic loads and vibration. This metric coarse thread coupling nut delivers consistent performance in extended shaft connections, threaded rod assemblies, and precision alignment applications where dimensional accuracy and material durability are non-negotiable.

Specification Summary & Compliance

This coupling nut features M12 x 1.75mm metric coarse threads with Class 6H thread fit tolerance per ISO standards, ensuring precise thread engagement. The 15mm outer diameter and 30mm length provide optimal strength-to-weight ratio for extended connections. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, confirming adherence to environmental safety standards for hazardous substances. The right-hand threaded, fully threaded coupling nut maintains consistent performance across industrial applications requiring reliable, corrosion-resistant metric fastening solutions.
