S-94579A650 3/8"-24 Weld Nuts

Key Features & Benefits at a Glance

• Superior welding stability with rectangular base design (1 1/8" length × 5/8" width) for maximum surface contact and resistance to rotation during assembly
• Enhanced thread reliability through Class 2B fine UNF threads ensuring precise fit and reduced risk of cross-threading in high-vibration environments
• Space-saving low profile barrel (3/32" height) ideal for confined spaces while maintaining 7/16" diameter for robust weld penetration
• Optimized material performance using steel construction for excellent strength-to-weight ratio and consistent welding characteristics
• Streamlined installation with pre-sized 29/64" mounting hole compatibility, reducing preparation time and improving workflow efficiency
• Long-term operational safety with full compliance to RoHS 3 and REACH environmental standards, ensuring hazardous substance-free manufacturing
• Right-hand thread orientation providing intuitive installation alignment for standard industrial equipment maintenance procedures

Professional Applications & Engineering Value

This low profile rectangular weld nut addresses critical challenges in heavy-duty fabrication where space constraints meet high-stress fastening requirements. The steel construction maintains structural integrity under thermal stress during welding operations, while the UNF fine thread (3/8"-24) delivers superior clamping force distribution compared to coarse threads. The rectangular base design prevents rotation during welding, eliminating the need for secondary stabilization in automotive frames, machinery skids, and structural steel assemblies. With its Class 2B thread fit, this weld nut ensures consistent engagement in high-cycle applications where vibration resistance is paramount, making it ideal for OEM manufacturing and MRO operations requiring reliable, heavy-duty fastening solutions.
