• Reliable Thread Performance: Class 2B thread fit with 1/2"-13 UNC coarse threading ensures smooth assembly and excellent resistance to vibration loosening in heavy-duty applications.
• Durable Steel Construction: Made from robust steel with a 3/16" thick base, offering high strength and longevity under mechanical stress and harsh industrial conditions.
• Precision Hole Compatibility: Designed specifically for 39/64" mounting holes, enabling accurate placement and reducing installation errors in fabricated structures.
• Right-Hand Thread Convenience: Standard right-hand thread direction facilitates quick and intuitive installation with common tools, improving workflow efficiency.
• Environmental Compliance Assurance: REACH and RoHS 3 compliant, ensuring safe usage in regulated industries and supporting corporate sustainability goals.

Professional Applications & Engineering Value

This low barrel rectangular weld nut is engineered to address common challenges in industrial fabrication, such as space constraints and the need for reliable, vibration-resistant fastening. The steel material and 3/16" base thickness provide exceptional load-bearing capacity, preventing deformation under high torque or dynamic loads. Its rectangular shape enhances stability during welding, minimizing misalignment in assembly lines for machinery, structural frames, and transportation equipment. The 1/2"-13 UNC coarse thread and Class 2B fit ensure consistent engagement with mating bolts, reducing the risk of cross-threading and thread wear over time. Ideal for heavy-duty applications like construction, automotive, and metalworking, this nut delivers secure, long-lasting performance while complying with industry standards for safety and efficiency.
