Key Features & Benefits at a Glance
- Corrosion-resistant brass construction ensures long-lasting performance in humid or chemically aggressive industrial environments.
- Precise Class 2B thread fit guarantees smooth assembly and a secure, reliable connection between threaded rods or components.
- External hex drive design allows for easy installation and removal using standard wrenches, improving maintenance efficiency.
- Fully threaded body provides maximum engagement strength and consistent load distribution across the entire coupling length.
- Fine UNF threading (3/8"-24) offers superior vibration resistance and reduced risk of loosening in dynamic applications.
- REACH and RoHS 3 compliance ensures environmental safety and meets stringent international regulatory standards for industrial use.
- Generous 1-3/4" length accommodates a wider range of connection gaps, enhancing versatility in complex assemblies.
Professional Applications & Engineering Value
This brass coupling nut is engineered to solve critical challenges in industrial settings where corrosion resistance and reliable threading are paramount. The UNF fine thread profile and Class 2B fit minimize backlash and prevent thread stripping, making it ideal for precision equipment, fluid handling systems, and machinery requiring vibration-resistant fasteners. Its fully threaded design and external hex drive simplify alignment and tightening in confined spaces, reducing installation time. The brass material naturally resists oxidation and galvanic corrosion, extending service life in marine, chemical, and electrical applications without requiring additional plating.
Specification Summary & Compliance
This coupling nut features a 3/8"-24 UNF fine thread with Class 2B tolerance for consistent fit and performance. Manufactured to standard inch system dimensions (1-3/4" length, 5/8" width), it complies with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, including exemption 6(c) for lead in copper alloys, ensuring it meets global environmental and safety standards for industrial components.
