Selecting the right option

Pick the size by the span range that covers the slotted nut you are turning: size 1 covers 20 to 42 mm, size 2 covers 45 to 90 mm and size 3 covers 95 to 165 mm. Where a nut has flats rather than slots, see the metric double open end spanners or the metric combination spanners.
