M12 signifies that the shank is 12 mm diameter. The length will vary. +++ Another tip: The A/F size of a standard M12 bolt or nut is 19mm, so close to 3/4" that the latter spanner will work - but be aware that this is the only co-incidence between metric and inch-based fastenings; and the M-series proportions don't follow a very consistent path!
