I'm a new comer who purchased a Large 4-6-0 Big Hauler and just purchased extra track. I need to unscrew the "small" screw on one side of the track.  before I can connet the track.  Where can I purchaser this tool?

Tool needed is 2mm Allen wrench

You probably have one in your tool box – if not,  shop  Lowe's, Home Depot or your local hardware store.
