  • Optimized Material Integrity using durable steel construction for high tensile strength and corrosion resistance in demanding environments
  • Secure Base Stability from the rectangular 7/8" x 7/16" base design, providing maximum surface contact and preventing rotation during welding
  • Streamlined Installation with pre-sized 1/4" hole compatibility, reducing setup time and improving assembly efficiency
  • Long-Term Operational Safety through full compliance with RoHS 3 and REACH regulations, ensuring environmental and workplace safety
  • Right-Hand Thread Convenience for standard tool compatibility and simplified fastening in industrial maintenance and production lines

Professional Applications & Engineering Value

This rectangular weld nut is engineered to address common industrial fastening challenges, such as space constraints and vibration-induced loosening. The low barrel profile minimizes protrusion, making it ideal for applications in automotive frames, machinery panels, and electrical enclosures where clearance is critical. Manufactured from high-grade steel, it offers excellent weldability and durability, resisting deformation under thermal stress during welding processes. The 10-32 UNF fine thread with Class 2B fit ensures tight, reliable connections that maintain integrity in high-vibration environments, reducing maintenance downtime. Its rectangular base enhances stability, preventing spin-out during installation and improving overall assembly precision for industrial weld nut applications in manufacturing and construction sectors.

Specification Summary & Compliance

This weld nut adheres to inch system dimensions, including a barrel diameter of 15/64", base length of 7/8", and compatibility with a 1/4" hole diameter. Thread specifications follow UNF fine thread standards with Class 2B tolerance for consistent fit. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring it meets stringent environmental and safety requirements for industrial use.
