Source levels
Main value = the modeled value (nominal, else the middle of min-max).
Grey under a value = its min-max, where the source gives both.
< / = = the source gives only that limit, modeled at it. ref = reference.
L2 = the standard itself (or its complete free preview, or the maker's drawing).
L1 = two or more independent sources agree: the release gate.
LO = one source only: printed amber and marked *.
c = a source value was corrected; the datasheet says how.
House convention = a detail no source dimensions, drawn to a stated house rule.
This size's values: L2 11-L16.
s = 4.91 Notes
4.82-5.00 s: the nominal is the wrench size (= s max); modeled at the middle of its band (ADR 0014). e is not modeled on its own: the regular hexagon gives e = 2s/v3 from the modeled s, = e min.
dw min sets the corner chamfer's face circle, (dw min + s) / 2; mw min is checked at mid-flat. Washer face c is not modeled (nuts are delivered without one); it is listed in the datasheet.
