• Standard barrel profile and 5/16" barrel height enable consistent weld penetration and alignment in automated or manual processes
• Right-hand thread direction compatible with standard tools, streamlining installation in high-volume production
• Compliance with RoHS 3 and REACH guarantees safe use in regulated industries without hazardous substances
• Optimized dimensions (0.305" barrel diameter, 3/64" base thickness) balance material efficiency with structural integrity

Professional Applications & Engineering Value

This round steel weld nut is engineered to address common challenges in fabrication, such as misalignment and weak joints in welded assemblies. The UNC coarse thread (1/4"-20) and Class 1B thread fit provide ample tolerance for variances in mating components, reducing installation time and preventing thread damage in high-vibration environments like automotive frames, machinery enclosures, and structural steelwork. Its standard barrel profile and generous base diameter ensure consistent heat distribution during welding, minimizing warping and enhancing load distribution. Made from robust steel material, it withstands extreme temperatures and mechanical stresses, making it ideal for repetitive industrial applications where reliability is critical.

Specification Summary & Compliance

This weld nut adheres to UNC thread standards with a Class 1B thread fit for coarse threading applications, ensuring dimensional accuracy per inch-based measurements. It meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, confirming the absence of restricted substances for industrial safety. Specifications include a barrel diameter of 0.305", barrel height of 5/16", base diameter of 1 1/4", and base thickness of 3/64", supporting consistent performance in welding operations.
