DU-BRO Blind Nuts – Permanent Mount RC Fasteners for Engines & Gear

The DU-BRO Blind Nuts are reliable, easy-to-install fasteners designed for RC builders who need strong, secure mounting hardware—especially in areas that are hard to access. These permanent-mount blind nuts are ideal for attaching engines, landing gear, cowls, hatches, and many other components where a standard nut simply won’t work.

Each blind nut is zinc plated to resist corrosion and provide long-lasting durability. Once installed, the prongs bite into the wood or mounting surface, creating a firm hold that won’t spin or loosen. This makes them perfect for glow, gas, and electric aircraft, as well as RC cars, boats, drones, robotics, and general hobby projects.

Because they mount from the inside, blind nuts allow you to tighten bolts from the outside of the model—great for cramped or enclosed spaces where reaching behind a firewall, fuselage, or bulkhead is difficult or impossible.

DU-BRO blind nuts are available in six popular thread sizes, making it easy to match them with your existing hardware:

• 2-56 – 0.25 g each

• 4-40 – 0.50 g each

• 6-32 – 0.50 g each

• 8-32 – 1.0 g each

• 10-32 – 1.25 g each

These nuts install quickly, hold securely, and are trusted by hobbyists for their strength and reliability. Whether you’re building a new airplane, reinforcing a landing gear mount, or upgrading old hardware, DU-BRO Blind Nuts provide a dependable and professional fastening solution for any RC project.
