TITLE
Size drawing, M8
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.
</ 2 = 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 17 - L17.
Notes
s: the nominal is the key size; the socket is modeled at the middle of its band.
