Hexagon Flange Nuts 1-20pcs 304 Stainless Steel Hex Flange Nuts DIN 6923 Vibration Resistant Self-Locking(M20x1PC)

Built-in Locking Feature：The serrated hex flange nut uses teeth under the flange that bite into the mounting surface, resisting loosening from vibrationBroad Surface Contact：Hexagon flange nuts distribute clamping force across a wider area than standard nuts, reducing the need for separate washersConsistent Torque Retention：A serrated flange nut maintains its grip under repeated thermal cycling or mechanical stressTime-Saving Assembly：Serrated flange hex lock nuts combine washer and locking functions in one piece, streamlining installation stepsReliable in Mechanical Applications：The hexagon hex flange nut secures components in machinery, automotive assemblies, and structural connections
