• Reliable thread engagement with Class 2B fit and 1/4"-20 UNC coarse threads, ensuring consistent performance and reducing cross-threading risks.
• Optimized for 5/16" hole diameter, facilitating precise alignment and faster assembly in manufacturing processes.
• Compliance with environmental regulations including REACH and RoHS 3, making it suitable for global supply chains and eco-conscious projects.
• Durable right-hand thread design maintains secure fastening under vibration and dynamic loads common in automotive and machinery applications.

Professional Applications & Engineering Value

This low profile rectangular weld nut is engineered to address common challenges in industrial assembly, such as space constraints and corrosion-induced failure. The 18-8 stainless steel material offers excellent resistance to rust and chemical exposure, extending service life in demanding sectors like automotive frame construction, electrical enclosures, and heavy equipment manufacturing. Its rectangular base and low barrel profile ensure maximum weld area and minimal protrusion, reducing the risk of loosening under stress. With UNC coarse threads and Class 2B fit, it provides quick, secure installation for high-volume production lines, while the right-hand thread direction aligns with standard tooling for efficient workflow integration.

Specification Summary & Compliance

This weld nut adheres to UNC thread standards with a Class 2B thread fit for consistent dimensional accuracy. Key specifications include a barrel diameter of 19/64", barrel height of 1/16", base length of 13/16", and compatibility with a 5/16" hole diameter. The product is manufactured in compliance with REACH (EC 1907/2006) and RoHS 3 (2015/863/EU) regulations, ensuring it meets stringent environmental and safety requirements for industrial fastener applications.
