- Easy installation and compatibility with coarse UNC threads and Class 1B fit, facilitating quick assembly with standard 4-40 fasteners.
- Stable base design featuring a 3/8" diameter and 1/32" thickness for enhanced load distribution and reduced risk of warping during welding.
- Optimized for inch-system applications with precise dimensions (0.141" barrel diameter, 1/8" height) for seamless integration in US-standard projects.
- Environmental compliance assurance meeting RoHS 3 and REACH standards, supporting sustainable and safe manufacturing practices.
Professional Applications & Engineering Value
This zinc-plated steel weld nut is engineered to address common challenges in welding operations, such as corrosion-induced failure and inconsistent thread alignment. The round barrel design and standard profile ensure uniform heat distribution during welding, minimizing distortion and providing a secure, permanent fastening solution. With its coarse UNC 4-40 threads and Class 1B fit, it offers excellent engagement with mating components, reducing cross-threading risks in high-vibration settings like automotive frames, machinery assemblies, and structural fabrications. The zinc plating adds a protective barrier, making it ideal for outdoor or humid environments where durability and long-term performance are critical. By integrating this nut, professionals achieve reliable, repeatable results while adhering to industry standards.
Specification Summary & Compliance
This weld nut adheres to UNC coarse thread standards with a Class 1B thread fit for consistent tolerances. Key dimensions include a barrel diameter of 0.141", barrel height of 1/8", base diameter of 3/8", and base thickness of 1/32". It is manufactured from zinc-plated steel and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental safety and material reliability.
