Professional Applications & Engineering Value

This rectangular low profile weld nut addresses critical challenges in industrial fabrication where space constraints and welding efficiency are paramount. The steel construction combined with the low barrel profile (1/16" height) enables flush mounting in tight clearances while maintaining full UNC coarse thread functionality. The rectangular base design distributes welding stress across a wider surface area (13/16" × 1/2"), preventing warping and ensuring permanent attachment in high-vibration environments. Class 2B thread fit guarantees consistent mating with corresponding fasteners, reducing assembly errors in automated production lines. These weld nuts are particularly valuable in automotive frames, machinery enclosures, and structural assemblies where reliable, permanent threaded points are essential for maintenance and component attachment.

Specification Summary & Compliance

This weld nut maintains Class 2B thread tolerance per UNC standards with 1/4"-20 coarse thread spacing and right-hand orientation. Critical dimensions include barrel diameter of 19/64", barrel height of 1/16", and base dimensions of 13/16" length × 1/2" width × 1/8" thickness. The product is manufactured to industry specifications for weld nut applications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for global industrial markets and restricted substance requirements.
