Professional Applications & Engineering Value

This A286 Stainless Steel Flange Nut is engineered to address critical challenges in high-strength fastening applications where corrosion, temperature extremes, and vibration are concerns. The external 12-point drive allows for higher torque application with standard wrenches, reducing installation time and improving safety in confined spaces. Its integrated flange distributes clamping force over a wider area, preventing surface damage and maintaining joint integrity under dynamic loads. Made from A286 stainless steel, it resists oxidation and retains strength at elevated temperatures, making it ideal for aerospace, automotive, and heavy machinery applications. The fine UNF threads and Class 3B fit ensure precise alignment and reliable performance in assemblies requiring minimal backlash and superior fatigue resistance.

Specification Summary & Compliance
