DU-BRO Metric Nylon Insert Lock Nuts – Zinc Plated RC Hardware

The DU-BRO Metric Nylon Insert Lock Nuts are strong, dependable fasteners designed to keep your RC hardware securely in place. Each nut features a nylon insert that grips the bolt threads as you tighten it. This prevents the nut from loosening due to vibration—a major benefit for RC airplanes, cars, boats, drones, and any model that experiences constant movement.

These nuts are made from aircraft-quality steel and finished with a zinc plating that protects them from rust and wear. This makes them a great choice for glow, gas, and electric models, as well as outdoor projects where moisture or fuel exposure can occur.

Metric lock nuts are commonly needed for:

• Motor and engine mounting

• Landing gear installation

• Servo trays and control systems

• Control horns, linkages, and pushrods

• RC car suspension and chassis parts

• Robotics, 3D-printed projects, and general workshop use

Because the nylon insert keeps the nut from backing out, these lock nuts give you a secure, long-lasting hold. They tighten smoothly, stay in place, and handle vibration extremely well.

Each package includes 4 nylon insert lock nuts, making them perfect for repairs, upgrades, or stocking your toolbox. If you want reliable fastening that won’t shake loose, the DU-BRO Metric Nylon Insert Lock Nuts are a must-have.
