Go away sprocket!

For those who asked, I have yet to pick up the repaired swinger, but my friend sent me this pic of it; Strength wise my mates husaberg has been happy to race supermoto with his similarly repaired swingarm for the past year or so.

I'm also having trouble finding long enough sprocket bolts. Or I should say without paying over $10 by the time I pay for shipping too....
Anyone have an opinion about whether or not using more "standard" flat socket head screws is ok? Like from image below?
The only real difference I see is that it'd be fully threaded.
