So I bought some Sugino Super Mighty, or maybe they just are the "mighty" since they dont say super-
anyways- I intended to use them on my track frame- get a track chainring and get chainring bolts to fit a single ring-
is that alright to do? Is there a major difference with the ones made for the track and the ones I have- except that they are a little bit thicker in the "spider" ?
for reference, these are the ones I bought-
any help would be great-
I just hope I dont have to end up re-selling them and getting the track specific ones, if that is whats needed-

They should work fine.....The only really big difference is the cranks you bought have a lip on inside that the inner chainring sits on. The tricky part is gonna be getting the correct spindle length (and taper) so you can run your track ring on the outside so it doesn't look silly....I'm not 100% sure but I think those cranks use an ISO tapered spindle rather than a JIS FWIW....

The ones made for Track had 151 BCD, whereas the road ones were 144 - copying Campagnolo to the very millimeter.
Of course you can use the 144 BCD ones for fixed gear. The rest of what kpug told you is also true, though I also am not sure of the taper and correct spindle length for that application. I'm sure there's someone here who can provide that answer. Perhaps T-Mar or nlerner - if the answer isn't sitting on Sheldon's site somewhere.

thanks for all the good info-
so the correct spindle legnth and taper is just for finding the correct bottom bracket for it right?
can there be any problem with this? will it be pretty easy to get the chain line straight?
I dont know if this helps at all- but they have this other logo on the inside of the cranks- looks like the njs logo but it says jic?

oooh i see what you guys are saying now- in order to get it straight and keep the chainline on the outside is the tricky part...
hmm- i hope i can

I think a 111mm campagnolo AC-H BB should do the trick quite nicely for use with the ring on the outside but you may have to grind off the inner rings tabs so they don't hit your stay. If you have an italian BB shell send me a PM.. I have a bunch of 111mm and 109mm campagnolo BBs that would work well for you. Otherwise, I believe the ISO AC-H BBs can be had relatively cheep.

Sugino Mighty (not Super, this may be true, but not sure), used a 109 mm asymmetric spindle.
