Professional Applications & Engineering Value

This rectangular weld nut delivers exceptional value in industrial applications where space constraints and vibration resistance are critical concerns. The zinc-plated steel construction provides superior corrosion protection for automotive chassis components, electrical enclosures, and machinery frames exposed to harsh operating conditions. The low-profile barrel design (0.8mm height) minimizes protrusion while maintaining sufficient material for consistent welding performance, addressing common challenges with weld nut displacement during high-temperature processes. With its M3.5 coarse thread and Class 6H fit, this fastener ensures reliable threaded connections in assembly lines where speed and precision are paramount, reducing installation time and preventing thread damage in metric fastener systems.

Specification Summary & Compliance

This metric weld nut features precise Class 6H thread fit according to ISO standards, with M3.5 coarse thread (0.6mm pitch) and right-hand orientation. The rectangular base measures 16×11 mm with 2.4 mm thickness, paired with 4.8 mm barrel diameter designed for 4.9 mm mounting holes. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental compliance for global industrial distribution and use.
