Mmmm, Thanks Trevor, no 2mm with 1mm pin listed. From Wiki,
There are a number of sizes listed below that appear to be quite similar, and while the tolerances of these connectors are typically indicated as ±0.05 or ±0.03 mm by the manufacturers, there is still ambiguity as to whether two sizes differing by only 0.05 mm (or where the specification is only given to the nearest 0.10 mm) warrants listing them separately here.[original research?]

The sizes are so close, could you measure it more accurately please ? A drill shank for the center pin fit?
