If, however, the holes are worn already you may still have a lot of slop in the hinge. You may need to replace the hinge. Measure the hole ID to see what you have. New MS20001-2 through -6 and -9 through -12 has a hole diameter of .093 +.005/-.000. The hinge pin is .089 +/-.001. Every hinge I have measured so far has come out on the large side when new: .096-.097. That is a lot of play right out the box. Another option is to use .094 stainless wire(standard size) or stainless 3/32 welding wire(.09375). You may need to ream the new hinge material to clean up the ID (reamers available in .0005" increments from McMaster, .0955 works well).

The ACS catalog only lists .089 pin material which I am assuming is the standard size pin. I suspect a little oversize would be appropriate.
