Was it a Polaris stock bolt that came out, or did you get the bolt from UTVGiant?
Either way, if you call UTVGiant I am sure they will tell you what you need, or maybe send you one.
But you'll want to call them, they don't check this forum often.
I believe those are metric. The size and pitch are M6 x 1.0. They are 1" in length.
You probably aren't going to find one with a torx head like that in your local hardware store, but you should be able to get one with a standard hex head to hold stuff down until your dealer can get you a bolt from Polaris.
