The throat opening tolerance, per the catalog page, is 0.13" for this shackle. Different sizes of shackles have different tolerances. Keep in mind that this pertains to new shackles only. This shackle is designed to have a 2.38" throat opening from the factory, but the factory allows 0.13" of tolerance due to the forging process, how thick the galvanizing is, etc. For shackles that are used in the field, any noticeable spread of the throat opening could be grounds for discarding the shackle, removing it from service. This is especially true if the shackle pin no longer threads naturally.
