4mm (M4) x 40mm Socket Head Cap Screws, 4pkg
The DU-BRO Metric Socket Head Cap Screws are strong, high-quality fasteners designed for RC hobbyists who want reliable hardware for building, repairing, or upgrading their models. These screws are made from durable steel and finished with a black oxide coating, giving them a clean, professional look while helping protect against corrosion and wear.
Because they use a socket (Allen) head, these screws provide excellent tool engagement. This makes them much easier to tighten than Phillips screws, especially in tight areas like engine compartments, servo bays, or other hard-to-reach spots. The socket head design also helps prevent stripping and allows you to apply the proper torque for a secure hold.
These metric cap screws are perfect for:
-
Mounting motors and engine components
-
Installing servos and electronic trays
-
Securing landing gear and structural supports
-
Attaching control horns and linkage parts
-
Robotics, 3D-printing builds, workshop projects, and more
Metric hardware is commonly used in many modern RC airplanes, cars, drones, and boats, making these screws a must-have for builders who want the right fit every time. They thread smoothly, hold tight, and offer dependable strength for glow, gas, and electric models.
