- Reliable load distribution thanks to the 45/64" flange diameter, reducing surface pressure and preventing loosening.
- High thread precision with Class 3B fit, ensuring secure, vibration-resistant fastening in critical assemblies.
- Quick installation efficiency from coarse UNC threads, speeding up assembly in time-sensitive operations.
- Durable construction with standard hex profile and 0.11" flange thickness, offering long-term stability under stress.
- Versatile compatibility for right-hand threaded applications, ideal for machinery, automotive, and structural uses.
Professional Applications & Engineering Value
This 7/16"-14 UNC flange nut is engineered to address common industrial challenges like vibration-induced loosening and corrosion in demanding settings. The black-oxide steel material provides a protective layer against moisture and chemicals, while the external 12-point drive allows for high-torque application with standard tools, minimizing wear. Its coarse thread spacing and Class 3B thread fit ensure rapid assembly and a tight seal, making it ideal for heavy-duty applications in automotive, construction, and machinery where reliability is critical. The integrated flange eliminates the need for separate washers, streamlining installation and reducing part counts in complex assemblies.
Specification Summary & Compliance
This flange nut adheres to UNC thread standards with a Class 3B thread fit for precise tolerance, and features a coarse thread spacing of 14 TPI. It meets common industrial specifications for dimensional accuracy, including flange diameter (45/64") and thickness (0.11"), and is manufactured from black-oxide steel for durability. Compliant with RoHS and REACH regulations, it ensures safe use in various engineering applications without hazardous substances.
