Exact dimensions. Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part. Mating features

sizes: 6 in table

Notes

Columns: thread, width across flats s, total height h, dome radius r, minimum thread depth t. Böllhoff gives the same h, s, r and t min for M4–M8.
M10 is drawn at SW17 and M12 at SW19 (KIPP); older editions also list SW16 and SW18. Thread drawn as a blind plain bore at the major diameter.
