DU-BRO Nylon Insert Lock Nuts – Standard Aircraft-Grade RC Hardware

The DU-BRO Nylon Insert Lock Nuts (Standard) are strong, dependable fasteners designed to keep your RC model’s hardware securely in place. Each nut includes a nylon insert that grips the bolt tightly, helping prevent it from loosening under vibration. This makes these lock nuts perfect for glow, gas, and electric models that experience constant movement during flight or operation.

• Mounting engines and motors

• Securing landing gear

• Installing servos and control systems

• Attaching linkages, control horns, and pushrods
