2768
ISO 2768 defines general tolerances for machined parts.

Where 2768 fits
Why 2768 is special
It lets a drawing omit a tolerance on every dimension by declaring one default class, which removes enormous clutter from engineering drawings and is why most dimensions carry no tolerance mark at all.

In historical numeral systems
Egyptian
2 lotuses, 7 coils of rope, 6 hobbles, 8 strokes
2 × 1,000 + 7 × 100 + 6 × 10 + 8 × 1 = 2,768. The signs are simply repeated and added; where they sit on the line is a matter of layout, not value.
Babylonian
4 corner wedges + 6 vertical wedges (sixties place), 8 vertical wedges (units place)
46 × 60 + 8 = 2768. Places are separated by a space on the tablet, with the higher place written first.
Systems that simply cannot reach this value are left out. Where a script needs a font most readers do not have, the reading is given instead of the glyphs — see number systems for each system in full.

Related numbers & connections
ISO 2768 supplies default tolerances so drawings need only mark critical dimensions, in the same way a gauge standard removes a decision from every railway design.

Technology & computing
ISO 2768 supplies default tolerances so a drawing need only mark the dimensions that are critical. Most numbers on an engineering drawing are governed by a standard referenced once in the title block.
