These are the same mounting screws used/included with the Crazy Bee F4 FC a necessary item when ripping around always good to have extras for when FPV happens.
This comes with 4 tall grommets, 1 short grommet, and 5 tall screws.
Another great Grommet/hardware option is our short grommets with 5 sets. We would recommend using these for an ultralight build for your brushless. Video coming soon.
