What is this for? Some type of hub? You probably don't need a full 1.75" of engagement and could counterbore your part to allow a more reasonable hex length.
Thanks COry for the reply, it would be a hub for a plastic wheel we got from our sponsor. Its about 1.5" long with a nub. Its a 1" od plug with a 1/2" bore.

Would you counterbore one side to .577" or similar and have the hex be 1.5" long? What would you suggest?

Thanks!
