Key Features & Benefits at a Glance
- Enhanced alignment tolerance with floating nut design that compensates for minor welding misalignments
- Superior corrosion resistance through zinc-plated steel construction for extended service life in harsh environments
- Reliable thread engagement with Class 2B UNC coarse threads ensuring consistent fastening performance
- Optimized welding stability from rectangular base design providing maximum surface contact area
- Lightweight retention system using 5052 aluminum retainer that maintains nut position during installation
- Industry-standard compatibility with 1/4"-20 UNC coarse thread patterns for broad application use
- Environmental compliance assurance meeting RoHS 3 and REACH standards for global manufacturing requirements
Professional Applications & Engineering Value
This zinc-plated steel weld nut addresses critical challenges in industrial assembly where vibration resistance and corrosion protection are paramount. The rectangular floating nut design solves alignment issues common in high-volume welding operations, allowing for ±1/16" adjustment capability while maintaining Class 2B thread fit precision. The 5052 aluminum retainer securely positions the nut during welding without adding significant weight, making it ideal for automotive frames, machinery fabrication, and structural steel applications where UNC coarse threads provide rapid assembly and reliable performance under dynamic loads. The combination of zinc plating and steel substrate ensures durability in exposed environments while meeting strict RoHS 3 and REACH compliance for international projects.
Specification Summary & Compliance
This weld nut maintains Class 2B thread fit per UNC standards with 1/4"-20 coarse thread spacing and right-hand direction. Manufacturing specifications include 1-3/4" base length, 9/16" base width, and 1/16" base thickness with 5052 aluminum retainer material. The product fully complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring adherence to international regulatory requirements for hazardous substances.
