The DU-BRO 3mm x 3mm Socket Set Screws are strong, reliable fasteners made for RC hobbyists. These tiny screws are perfect for securing pushrods, wheel collars, gears, control arms , and other rotating parts in RC airplanes, cars, boats, helicopters, and drones. They use a socket (Allen) drive, which gives you a solid grip with your hex wrench and helps prevent stripping. Their short 3mm length makes them great for tight spaces or places where a small, low-profile screw is needed. Once tightened, they sit neatly inside couplers, control horns, shaft adapters, and other hardware without getting in the way. Made from high-strength steel, these screws hold tight even in high-vibration setups like glow engines, gas engines, or high-RPM electric systems. The precise threading makes them easy to install and ensures a secure fit with metric parts. These set screws are a must-have for any RC builder’s toolbox. Whether you’re building a new model, upgrading parts, or doing routine repairs, the DU-BRO 3mm x 3mm Socket Set Screws give you dependable and long-lasting performance. 4/pkg. Show more
