S-90860A120 3/8"-16 Weld Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance from 18-8 stainless steel construction for long-term reliability in harsh, humid, or chemically aggressive environments
• Excellent weld integrity with a round base design that ensures strong, consistent fusion to workpieces for permanent, vibration-resistant fastening
• Effortless installation thanks to the coarse UNC thread and Class 2B fit, enabling quick assembly and reducing labor time
• Enhanced load distribution from the 1" base diameter, minimizing surface stress and preventing material deformation
• Secure thread engagement with a 7/16" barrel height providing ample depth for reliable thread contact and joint stability
• Right-hand threading compatibility for standard tooling and straightforward integration into existing industrial systems
• Compliance with strict environmental regulations including RoHS 3 and REACH, ensuring safe use in regulated industries

Professional Applications & Engineering Value

This 18-8 stainless steel round weld nut delivers critical performance in demanding industrial settings where corrosion and mechanical stress are constant challenges. Its UNC coarse thread design prevents cross-threading during high-speed assembly, while the Class 2B thread fit maintains consistent clamping force in vibrating equipment. The standard barrel profile and generous 1" base diameter create an optimal welding surface for structural applications in machinery frames, transportation equipment, and outdoor infrastructure. Engineers specify this weld nut for permanent installations where disassembly isn't required, providing a cost-effective alternative to threaded inserts while offering superior pull-out resistance. The combination of stainless steel material and compliant manufacturing makes it ideal for food processing, marine, and chemical processing applications where both durability and regulatory compliance are mandatory.
