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 vibrat
