This M3x4mm hex socket screw set is suited to typical fastening roles on electric model cars and comparable radio-controlled platforms. The set comprises 10 pcs, suitable for securing chassis plates, body mounts, gearboxes and accessory brackets that take M3 fasteners.
Compatibility is broad across parts that accept M3 screws; always verify the component thread before installation. Employ a correctly sized hex driver to avoid rounding the socket head and apply controlled torque to prevent thread stripping or damage to lightweight components.
Store these screws with your basic tool kit for quick swaps during events or roadside fixes. They serve as conventional fastening hardware within RC builds and provide secure joins without modifying drive characteristics.
