| I have not looked at them (being very new in the logo arena), but my first guess would be that they are probably very finly serrated or cuped on the end; after use the serrations and/or cupping would not hold as well as they/it would be damaged.
What i find interesting is that there is only one screw and a very small one at that.
i would be tempted to grind a flat on the motor shaft or to drill and tap a second screw.
