you're not going to find that at HD. Even a specialty fastener supply store probably wouldn't have it.

You could probably find something with the same threading, maybe you'll find one with a smooth shaft, but smooth shaft at x length and an overly large cheesehead... maybe not. I think the parts counter at canadian tire can give you the proper thread count/spacing to let you know what you're looking for in terms of the size.

edit: generally HD and CT don't carry very fine machine screws. You'll have to try a specialty fastener supply store if you have one where you are.
