Key Features & Benefits at a Glance
- Enhanced Alignment Tolerance: Floating nut design compensates for minor misalignments during welding, reducing installation time and preventing thread damage.
- Superior Stress Distribution: Rectangular base with 1 3/4" length and 9/16" width provides a larger weld surface area for increased joint stability under load.
- Reliable Thread Performance: Class 2B UNF fine thread (1/4"-28) ensures precise, vibration-resistant connections in right-hand threaded assemblies.
- High-Strength Material Construction: C1008/C1010 steel base and retainer offer excellent weldability and mechanical durability in industrial environments.
- Optimized Welding Efficiency: 1/16" base thickness allows for rapid heat transfer during welding while maintaining structural integrity.
- Environmental Compliance Assurance: Meets RoHS 3 and REACH standards, ensuring safe use in regulated manufacturing applications.
Professional Applications & Engineering Value
This rectangular weld nut solves critical alignment challenges in fabricated structures and machinery assemblies. The floating nut design allows ±2° angular adjustment during installation, preventing cross-threading in pre-tapped components while maintaining Class 2B thread integrity. Manufactured from C1008/C1010 steel, the nut demonstrates exceptional weld penetration characteristics when joining to similar materials, distributing thermal stresses across the rectangular base to minimize distortion. The 1/4"-28 UNF fine thread provides 30% more engagement points than coarse threads, making it ideal for vibration-prone applications in automotive frames, electrical enclosures, and structural steel assemblies where right-hand threading is standard.
Specification Summary & Compliance
Manufactured to UNF thread standards with Class 2B fit tolerance for consistent engagement. Base dimensions: 1 3/4" length × 9/16" width × 1/16" thickness. Complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental directives. Retainer material conforms to C1008/C1010 steel specifications for welding applications.
