- Easy installation and removal with standard external hex drive design, compatible with common wrenches for efficient assembly
- Durable performance in inch-system applications, featuring a compact 3/16" width and 1/16" height for space-constrained assemblies
- Compliance with stringent regulations including RoHS 3 and REACH, ensuring safe use in regulated industries and international markets
- Reliable right-hand thread direction for consistent fastening in standard industrial and precision mechanical applications
Professional Applications & Engineering Value
Engineered for demanding environments, this 3-56 UNF brass hex nut combines excellent corrosion resistance with precise Class 2B fine threading to address common industrial challenges such as galvanic corrosion and thread wear. The UNF (Unified National Fine) thread type ensures tighter seals and better load distribution in vibration-prone assemblies, making it ideal for precision equipment, electrical enclosures, and marine components. Its brass material naturally resists rust and conducts electricity safely, while the standard hex profile allows for quick installation with standard tools, reducing assembly time and maintenance costs in B2B manufacturing and MRO operations.
Specification Summary & Compliance
This hex nut adheres to inch system standards with a 3-56 UNF fine thread and Class 2B thread fit for consistent dimensional accuracy. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and regulatory acceptance. The external hex drive and right-hand thread direction follow common industrial specifications for reliable performance in precision fastening applications.
