DU-BRO Stainless Steel Nylon Insert Lock Nuts – RC Hardware (4/pkg)

The DU-BRO Stainless Steel Nylon Insert Lock Nuts give RC builders a strong, secure, and rust-resistant option for fastening important components. Made from high-quality stainless steel, these nuts are perfect for models that face fuel exposure, moisture, or outdoor conditions. They won’t rust, weaken, or degrade over time, making them a long-lasting choice for any RC project.

Each nut includes a nylon insert that locks onto the bolt threads as you tighten it. This prevents the nut from loosening due to vibration—something every RC aircraft, car, drone, and boat experiences during normal use. The self-locking design keeps your hardware tight and reliable, even after repeated flights or runs.

These lock nuts are ideal for:

• Engine and motor mounting

• Servo and electronics installation

• Landing gear blocks

• Control horns, linkages, and pushrods

• RC vehicle chassis and suspension

• Robotics, DIY builds, and workshop projects

Because they resist corrosion and hold tight under vibration, these nuts provide dependable performance whether you fly glow and gas models or run electric cars and boats.

Each package includes 4 stainless steel nylon insert lock nuts, so you can easily upgrade old hardware, complete repairs, or keep spares in your toolbox.

If you want hardware that stays secure, looks clean, and lasts a long time, the DU-BRO Stainless Steel Nylon Insert Lock Nuts are an excellent choice for your RC builds.
