Essential Fastener ProtectionSecure your model hardware with confidence
Keep your critical hobby assemblies tight and secure with high-quality Dubro Washers. Designed for a wide range of RC applications, these versatile RC fasteners offer both flat washer and split lock washer options to handle surface protection and anti-vibration needs. Whether you are assembling an RC plane, car, or boat, trust Dubro Washers for reliable performance on every build.
Precision Model HardwareMaximum security against severe vibration
Dubro Washers are an essential addition to any RC mechanic's workshop toolbox or field kit. Available in both versatile flat and split lock styles, these high-grade RC hardware washers solve common mounting and structural challenges during assembly and maintenance. Use the flat washer configuration as precision shims or spacers to distribute fastener pressure evenly, preventing screw heads from sinking into or pulling through soft materials like balsa wood, plastic, or fiberglass. For high-vibration applications such as gas motor mounts, nitro engines, and high-rpm brushless setups, the split locking option ensures your hardware stays firmly locked in place without backing out over time. Choose durable Dubro Washers to keep your scale models built tough and ready for action.
