Flange Lock Nuts

Flange lock nuts are an essential component in any application where vibration or movement could loosen a standard nut. Their unique design features a flange that provides extra support and grip, helping to keep the nut securely in place. By using flange lock nuts, you can help prevent the loosening or dislodging of nuts, reducing the risk of damage or safety hazards. Our flange lock nuts come in a range of sizes and finishes, making them suitable for a wide range of applications.
