Tim, You can use whatever you can match the size for a drill and the pin. We've used 20 penny nails, even balance rail pins. The hole size must match the pin or else you could generate a cr--r--ra--ck when you tap in that pin and bend it backward. If the hole is too big, and I saw this on a brand new Baldwin, the hitch pin actually will be turned around by the string tension and a stable tuning will be ever so difficult. Weird, wierd stuff!
