- Space-saving low-profile design featuring a 0.8mm barrel height for applications with tight clearance requirements
- Reliable thread performance with Class 6H metric coarse threads ensuring consistent engagement and vibration resistance
- Optimized for 5.3mm mounting holes with precise barrel diameter matching for secure welding placement
- Durable steel construction offering excellent strength and corrosion resistance for long-term industrial use
- Environmental compliance assurance meeting RoHS 3 and REACH standards for safe global manufacturing applications
- Right-hand thread orientation providing standard installation compatibility across metric fastener systems
Professional Applications & Engineering Value
This low profile rectangular weld nut solves critical space constraints in industrial applications where traditional fasteners cannot fit. The M4 metric coarse thread (0.7mm pitch) with Class 6H fit maintains precise tolerance control, preventing cross-threading while accommodating thermal expansion in welded assemblies. The steel material provides structural integrity under vibration and load stress, making it ideal for automotive frames, machinery panels, and electrical enclosures. The rectangular base design distributes welding heat evenly, reducing distortion risk and ensuring permanent fixation in 5.3mm prepared holes—eliminating the need for additional retention hardware and streamlining production workflows.
Specification Summary & Compliance
This weld nut maintains ISO metric thread standards with Class 6H internal thread tolerance for consistent mating with Class 6g external threads. Manufacturing adheres to welding nut specifications with precise dimensions: 5.2mm barrel diameter, 0.8mm barrel height, and 16x11mm rectangular base. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring hazardous substance restrictions are met for global industrial distribution and use.
