Professional Applications & Engineering Value

This low profile rectangular weld nut addresses critical space constraints in industrial assembly while maintaining structural integrity. The steel construction combined with UNF fine threading creates exceptional vibration resistance in automotive frames, machinery enclosures, and structural frameworks where loosening under dynamic loads is a primary concern. The rectangular base design distributes stress evenly across welded surfaces, preventing distortion and ensuring consistent Class 2B thread fit throughout the product lifecycle. Particularly valuable in high-volume manufacturing environments, these weld nuts streamline production with their standardized 5/16" hole diameter compatibility and reliable right-hand threading that maintenance teams can service without specialized tools or training.

Specification Summary & Compliance

Manufactured to precise dimensional standards with Class 2B thread fit tolerance ensuring consistent engagement with mating components. The UNF fine thread specification (1/4"-28) provides superior holding power in vibration-prone applications. Compliant with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) environmental regulations, confirming adherence to international substance restriction standards. Barrel dimensions (19/64" diameter × 1/16" height) and base configuration (13/16" × 1/2" × 1/8") are engineered for optimal welding performance and structural integration.
