They are not standard machine-screw type threads. They are more like sheet-metal or wood-screw threads.

The mounting screws are designed to be screwed into the wood or plastic frame of an RC car or plane. For robotics applications, I generally replace them with M3 or 4-40 hardware.

The shaft fixing screw goes into the core of the nylon servo shaft. In a pinch, most any screw with similar diameter threads will work there.

Both mounting and shaft fixing screws have a major diameter of about 2.33mm. The thread length is 9mm long on the mounting screws and 5mm on the shaft fixing screw.
