Professional Applications & Engineering Value

This 316 stainless steel flange nut with 6-32 UNC coarse thread is engineered to address common industrial challenges such as corrosion-induced failure and joint loosening under dynamic loads. The external hex drive allows for high-torque application, ensuring a secure fit in machinery, automotive assemblies, and outdoor structures. Its integrated flange acts as a built-in washer, distributing clamp load over a wider area—this minimizes stress concentration on soft materials and painted surfaces, reducing the need for additional components. The Class 2B thread fit and coarse threading provide excellent resistance to vibration and cross-threading, making it a reliable choice for maintenance-heavy environments. Ideal for industrial fastening in aggressive settings, this nut delivers long-term performance while meeting strict environmental compliance standards.
