Professional Applications & Engineering Value

This rectangular weld nut delivers exceptional engineering value in demanding welding applications where corrosion resistance and space constraints are critical factors. The 18-8 Stainless Steel composition provides inherent protection against rust and chemical degradation, making it ideal for automotive assemblies, machinery frames, and outdoor equipment. The low-profile barrel design (7/16" diameter × 3/32" height) solves clearance challenges while maintaining structural integrity. With 3/8"-24 UNC fine threading and Class 2B thread fit, this fastener ensures precise, vibration-resistant connections in high-stress environments. The rectangular base (1 1/8" × 5/8") offers superior weld surface area, preventing rotation during installation and distributing loads effectively across welded joints.

Specification Summary & Compliance

This weld nut features precision UNC thread specifications with Class 2B thread fit for consistent engagement and reliable performance. Manufacturing adheres to strict dimensional tolerances including barrel diameter (7/16"), barrel height (3/32"), and base dimensions (1 1/8" length × 5/8" width). The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and regulatory adherence for industrial applications worldwide.
