Du-Bro Part - 128
The DU-BRO Mounting Bolts & Blind Nuts set gives you everything you need for secure and professional engine mounting on your RC aircraft. Engine mounting hardware must be strong, reliable, and able to handle vibration, and DU-BRO delivers exactly that with high-quality components designed for long-lasting performance.
Each package includes four complete hardware sets, and every set contains:
-
4 bolt
-
4 flat washer
-
4 lock washer
-
4 blind nut
This combination ensures a tight, vibration-resistant mount that stays secure through takeoff, flight, and landing. The lock washer helps prevent hardware from backing out, while the blind nut installs on the inside of the firewall, creating a strong anchor point that won’t pull through the wood.
These mounting kits are perfect for glow, gas, and electric engines, as well as for mounting motor mounts, landing gear blocks, servos, or any component that needs strong support. DU-BRO hardware is known for precision threading, reliable fit, and consistent strength—qualities that make a noticeable difference in high-vibration RC applications.
