Key Features & Benefits at a Glance

  • Enhanced weld integrity with rectangular base design providing superior surface contact and preventing rotation during welding
  • Space-saving low profile barrel (1/32" height) enables installation in confined spaces without compromising strength
  • Reliable coarse threading (10-24 UNC) with Class 2B fit ensures smooth assembly and reduced cross-threading risks
  • Optimized for 1/4" mounting holes with precise 15/64" barrel diameter for secure fit and alignment
  • Durable steel construction delivers exceptional tensile strength and corrosion resistance for harsh industrial environments
  • Right-hand thread orientation provides standard fastening compatibility with common industrial equipment
  • Environmental compliance with RoHS 3 and REACH regulations ensures safe usage in regulated applications

Professional Applications & Engineering Value

This low-profile rectangular weld nut solves critical challenges in industrial assembly where space constraints and vibration resistance are paramount. The steel construction combined with the rectangular base design creates exceptional weld surface area, preventing loosening under dynamic loads. The 10-24 UNC coarse thread configuration maintains reliable performance in high-vibration environments common in machinery, automotive frames, and structural fabrications. Engineers specify this Class 2B thread fit weld nut for applications requiring precise alignment in 1/4" mounting holes, where the low-profile barrel enables flush mounting without protrusions. The combination of right-hand threading and robust material properties makes this weld nut ideal for permanent installations in heavy equipment, conveyor systems, and industrial enclosures where disassembly isn't required.

Specification Summary & Compliance

This weld nut maintains Class 2B thread fit tolerances per UNC standards with coarse thread spacing for reliable engagement. Manufacturing conforms to standard weld nut specifications with precise dimensions: 15/64" barrel diameter, 1/32" barrel height, and 7/8"×7/16" rectangular base. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe usage in industrial applications worldwide.
