S-94579A790 5/16"-18 Weld Nuts

Key Features & Benefits at a Glance

• Superior corrosion resistance through zinc-plated steel construction, extending service life in harsh industrial environments
• Enhanced welding stability with rectangular base design (63/64" x 5/8") providing maximum surface contact for secure joints
• Space-saving installation thanks to low-profile barrel height (3/32") ideal for confined assembly areas
• Reliable thread engagement with UNC coarse threading (5/16"-18) ensuring quick assembly and vibration resistance
• Precision fit guarantee through Class 2B thread tolerance for consistent performance in high-volume applications
• Optimized barrel design (23/64" diameter) creates perfect alignment for 3/8" mounting holes during welding operations
• Regulatory compliance assurance meeting both RoHS 3 and REACH standards for global industrial use

Professional Applications & Engineering Value

This zinc-plated steel weld nut solves critical challenges in metal fabrication and assembly lines where corrosion resistance and space constraints coexist. The low-profile rectangular base distributes welding stress evenly across wider surfaces, preventing warpage in thin-gauge materials while the UNC coarse threading maintains reliable fastening under vibration-prone conditions. Engineered for industrial welding applications requiring repeated disassembly, the Class 2B thread fit ensures consistent engagement without cross-threading issues. The zinc plating provides essential protection against oxidation in manufacturing environments exposed to moisture or chemicals, making these weld nuts ideal for automotive frames, electrical enclosures, and heavy equipment manufacturing where durability and regulatory compliance are mandatory.

Specification Summary & Compliance
