Where can I get the small hex wrench that comes with the FT-802?

Unfortunately, American Hakko Products does have a part number for this hex wrench. If it ended up being lost, it would have to be replaced by a 1.27mm hex wrench that could be ordered online. If you would like the original hex wrench that came with the unit, a RFQ would have to be opened by contacting our Customer Service department at 1-800-88-HAKKO (42556).
