Although I appreciate the time, I have no idea what this says. I found this website, which says that the bolt head is weird, if it's not then I'll be fine, but I don't want to start on it & then find out that I need some weird tool for it. I'm guessing it means its a 3/8" hex head bolt just like Jerry said.Here's the one you may be looking for.

x50000 on grabbing a T-55. I think I have at least 5 of them floating around in my garage at all times. The Walmart near my house has stanley torx sets for 10 bucks. Definitely worth picking up if you don't have any torx sets. Stanley is about as cheap as I would go or you are going to wind up shearing the little head tips off on the cheaper ones in a crucial situation. Usually at a time when no auto parts stores will be open.Is this for your '97 TJ? If so, my '97 TJ uses standard hex head bolts to hold the starter in. I just had it out to replace my clutch 4 weekends ago. But yes, Sears and NAPA have complete sets of Torx head adapters. Just make sure you also buy a separate T-55 since most sets don't include a T-55 but your Jeep uses that size in several locations.
