Serrated Flange Nuts – Built-In Grip for Secure, Vibration-Resistant Fastening
 
Our Serrated Flange Nuts combine a wide integrated washer base with radial serrations to deliver strong, secure fastening without the need for a separate washer. The serrated flange bites into the mating surface, helping to prevent loosening from vibration and distributing pressure evenly to reduce surface damage. Available in zinc-plated and stainless steel, these nuts are perfect for automotive, machinery, and structural applications.
