Surface Issue when exporting to STEP

Morning all,

I have an issue with a couple of my parts when exporting to a STEP file,

I have some M5 self tapping screws that export with a sharp tip (at the wrong end) which comes out looking pretty cool but not very representative of the real thing,

Is there some settings I need to adjust in the exporting that I have missed?
