Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
- High-strength Grade 5 performance ensures reliable load-bearing capacity for heavy-duty applications
- Coarse UNC threading (1 3/8"-6) provides faster assembly and reduced cross-threading risk compared to fine threads
- Class 2B thread fit guarantees consistent engagement and vibration resistance in right-hand threaded assemblies
- Thin profile design saves space and weight while maintaining full ASME B18.2.2 compliance
- External hex drive compatibility enables standard tool usage for efficient installation and removal
- Regulatory compliance assurance with RoHS 3 and REACH standards for global supply chain integration
Professional Applications & Engineering Value
This Grade 5 thin hex nut delivers critical engineering advantages through its zinc-plated steel composition and coarse UNC threading. The combination addresses common industrial challenges like corrosion-induced failure and assembly time inefficiencies. The 1 3/8"-6 thread size with Class 2B fit maintains precise tolerances under vibration, making it ideal for structural steel connections, heavy machinery, and transportation equipment where right-hand thread fasteners require consistent clamping force. The thin hex nut profile proves particularly valuable in space-constrained assemblies without compromising the ASME B18.2.2 dimensional integrity, while the external hex drive ensures compatibility with standard wrenching tools across maintenance and production environments.
Specification Summary & Compliance
Manufactured to ASME B18.2.2 specifications with Class 2B thread fit tolerances for consistent performance. The 1 3/8"-6 UNC coarse thread maintains standardized spacing compatibility, while dimensional accuracy is verified at 2 1/16" width and 25/32" height. Full compliance with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations ensures environmental responsibility and global market acceptance.
