- All dimensions are in millimetres.
- AS 2129 Tables D, E, F and H keep the inch-based drilling of the old BS 10 tables, converted to millimetres, so they generally mate with BS 10 flanges of the same table.
- Values are nominal, compiled from published copies of the standard; blank cells (—) are values not confirmed from the sources available. Verify against the current edition before design, purchase or fabrication.
