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 8 - LO 6.
Notes
d, d1 and z are the 3/8-16 row's; D, D1, t and e the 1/4-20 row's (Tables 1-2, Fig. 1). Thread diameters at the band midpoint, else the basic (designation nominals, ADR 0014). Figure 1 values are figure reads of the preview: one lineage (LO), modeled at the limit. H, de, n, m: house rule (#1120 items 1B, 8 A), not any maker's design.
