   "NEMA 24 (60 mm face) and NEMA 42 (110 mm face) steppers follow the NEMA ICS 16 convention that the name is the face width in tenths of an inch (24 = 2.4 in, 42 = 4.2 in). The face, hole pattern and pilot are fixed by the frame; shaft diameter, shaft length and body length are not, and the makers read for this page do not all agree.",
   "Numbers: the NEMA 24 face, hole spacing, hole diameter and pilot come from the igus MOT-AN-S datasheet's dimensions table, whose column labels are not printed in the extract read; they were assigned by matching the NEMA 23 row of the same table to published NEMA 23 values (56.4 face, 47.14 spacing, 6.35 shaft, 38.10 pilot, as on the 'NEMA 8 to 34' page). The igus shaft column is therefore listed as read, with the other makers beside it; the igus length columns are not used. Nanotec's NEMA 24 and 42 pages link STEP and PDF files for each motor but their dimensional drawings are images, so no numbers come from them beyond the 60 mm and 110 mm flange size. NEMA 42 numbers come from Hallikainen's frame table (inches, converted here at exactly 25.4) and JLC Motion Control, which agree on the spacing and the pilot; the hole diameter and pilot depth are Hallikainen only. Hallikainen has no NEMA 24 row.",
