DU-BRO Mounting Bolts & Blind Nuts – RC Engine Mounting Hardware Kit

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.

Available in multiple sizes:

• #125 – 3 grams per package

• #127 – 8 grams per package

• #128 – 12 grams per package

These weight differences reflect hardware size options, allowing you to choose the right set for your engine or model.

Whether you're building a new aircraft, replacing old hardware, or upgrading to something more dependable, the DU-BRO Mounting Bolts & Blind Nuts provide the strong, secure engine installation your model needs to perform safely and consistently.
