S-93355A550 M18 x 54 mm DIN 6334 Coupling Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction for extended service life in harsh industrial environments
• Exceptional tensile strength and load distribution capabilities due to the fully threaded, heavy-duty design
• Precise and reliable mating ensured by the Class 6H thread fit, minimizing the risk of cross-threading and assembly failures
• Optimized for high-torque applications with the external hex drive profile, allowing for secure tightening with standard tools
• Enhanced assembly efficiency with the coarse 2.5 mm thread pitch, enabling faster installation and disassembly
• Guaranteed dimensional consistency and interchangeability through strict adherence to DIN 6334 standards
• Compliance with environmental regulations (RoHS 3), making it suitable for use in regulated industries and global supply chains

Professional Applications & Engineering Value

This M18 coupling nut is engineered to solve critical connection challenges in demanding industrial applications. Manufactured from zinc-plated steel, it provides a robust, corrosion-resistant barrier, significantly increasing the longevity of assemblies exposed to moisture and corrosive agents. The fully threaded design and coarse metric thread (2.5 mm pitch) ensure a deep, secure engagement, making it ideal for joining long threaded rods or extending studs in construction, machinery framing, and heavy equipment. The external hex drive and compliance with the DIN 6334 specification guarantee a perfect fit and reliable performance under high vibrational loads, reducing maintenance downtime and preventing costly connection failures.

Specification Summary & Compliance

This coupling nut features an M18 x 2.5 mm metric coarse thread with a precision Class 6H thread fit as per ISO standards. The manufacturing and dimensional specifications strictly conform to DIN 6334. The product is RoHS 3 (2015/863/EU) compliant with exemption 6(a)-I for lead as an alloying element in steel, ensuring it meets stringent environmental and safety regulations for industrial components.
