Metric Flange Nuts, Prevailing Torque, Class 10.9 Plain Steel, M14 x 2.0
Class 10.9 Metric Sized Prevailing Torque Hex Flange Nuts
|
Metric Prevailing Torque Flange Nuts in Plain Finish Class 10.9 Steel (also known as Flange Lock Nuts, All-Metal Locking Flange Nuts, or Stover Flange Nuts) combine the load-distributing benefits of a flange nut with the vibration-resistant properties of a prevailing torque lock nut, delivered in an uncoated finish for maximum versatility. The all-metal locking mechanism features a distorted thread portion at the top of the nut that creates friction against the bolt threads, providing consistent resistance to loosening caused by vibration, shock, and dynamic loads without relying on nylon inserts that degrade at high temperatures. The plain steel finish is ideal for applications where the assembly will be painted, powder-coated, or plated after installation, or where operating temperatures exceed the limits of zinc plating. Manufactured from high-strength Class 10.9 alloy steel, these prevailing torque flange nuts are engineered for demanding automotive, heavy equipment, machinery, and industrial applications where maximum clamping strength, reliable locking performance, and finish flexibility are required.
