Non-standard idler pulley bolt?

[LuckyBambu]

So I went to change my tensioner and idler pulleys tonight, all went well EXCEPT my 3.5" smooth idler. I don't seem to have a 15mm bolt on this one... it's more like some kind of a star pattern in the middle?

Is anybody familiar with this? Documentation I see seems to list 15mm bolts for all the pulleys.

I don't have a whole bunch of tools, so if anybody has any ideas what this might be I would be appreciative.

ive found cheap sets of torx for like 5 to 10 bucks, they snap on to a 3/8 ratchet.

Tea Time suggested a T50?

t45, t50ish

A T45 worked... it might have been a T47... was a little bit bigger than the T45 it seemed but the T45 worked.

Victory over Pulleys day.
