   "Thread columns are Lapp's table T21: D1 is the thread outer diameter, D2 the core diameter, D3 the panel hole, printed in the table as, e.g., '12.3 –0.2' (the number shown with its tolerance symbol as printed). M12, M16, M20, M25, M32, M40, M50, M63, M75, M90, M110 are the EN 60423 series (screw connections to EN 50262); M18, M24, M30, M36, M45, M56, M72, M80, M105 are DIN 13 sizes (screw connections to DIN 89280). The hole gauge uses the printed D3 for M12–M63.",
   "Cable range, thread length, height and key size are VIOX's standard nylon series, one vendor's numbers, so other makers (Lapp Skintop, Jacob, Heyco) differ. Key size is 'body / cap' (the hex on the thread body and the hex on the dome cap). VIOX's chart cites no standard for these and gives no panel hole for its metric glands; the hole shown here is Lapp's.",
   "Thread lengths in the table are VIOX's. Lapp's metric gland dimensions (wrench size, length, clamping range per article) are in its catalogue pages that could not be read, and Jacob's PERFECT datasheet prints columns A, C, L, SW1, SW2, H without defining them, so neither is reproduced.",
   "Also published in T21 but not drawn: installation space Ø A for each wrench size (e.g. SW 22 → Ø 25.0 mm), tightening torques (plastic M12 1.5 Nm to M63 16 Nm; metal M12 8 Nm to M63 20 Nm), and NPT hole sizes.",
   "PG glands are on the page cable-glands-pg-thread. McMaster-Carr's cord-grip and cable-gland pages (M12, M32, M40 and PG sizes appear in its thread-size URLs) carry per-part STEP; linked, not copied."

M12, M16, M20, M25, M32, M40, M50, M63, M75, M90, M110 are the EN 60423 series (screw connections to EN 50262); M18, M24, M30, M36, M45, M56, M72, M80, M105 are DIN 13 sizes (screw connections to DIN 89280). The hole gauge uses the printed D3 for M12–M63.\n- Cable range, thread length, height and key size are VIOX's standard nylon series, one vendor's numbers, so other makers (Lapp Skintop, Jacob, Heyco) differ. Key size is 'body / cap' (the hex on the thread body and the hex on the dome cap). VIOX's chart cites no standard for these and gives no panel hole for its metric glands; the hole shown here is Lapp's.\n- Thread lengths in the table are VIOX's. Lapp's metric gland dimensions (wrench size, length, clamping range per article) are in its catalogue pages that could not be read, and Jacob's PERFECT datasheet prints columns A, C, L, SW1, SW2, H without defining them, so neither is reproduced.\n- Also published in T21 but not drawn: installation space Ø A for each wrench size (e.g. SW 22 → Ø 25.0 mm), tightening torques (plastic M12 1.5 Nm to M63 16 Nm; metal M12 8 Nm to M63 20 Nm), and NPT hole sizes.\n- PG glands are on the page cable-glands-pg-thread. McMaster-Carr's cord-grip and cable-gland pages (M12, M32, M40 and PG sizes appear in its thread-size URLs) carry per-part STEP; linked, not copied.\n\nthread  standard  thread OD D1 (mm)  core D2 (mm)  panel hole D3 (mm, Lapp)  VIOX model  cable range (mm)  thread length (mm)  height (mm)  key size body / cap (mm)\nM12 × 1.5  EN 60423  12  10.6  12.3 (–0.2)  1001-M1265  3–6.5  8.5  26  18/15\nM12 × 1.5  EN 60423  12  10.6  12.3 (–0.2)  1001-M1208  4–8  8.5  26  18/19\nM16 × 1.5  EN 60423  16  14.6  16.3 (–0.2)  1001-M1607  3–7  10  29  22/19\nM16 × 1.5  EN 60423  16  14.6  16.3 (–0.2)  1001-M1608  4–8  10  29  22/19\nM16 × 1.5  EN 60423  16  14.6  16.3 (–0.2)  1001-M1610  5–10  10  30  22/22\nM20 × 1.5  EN 60423  20  18.6  20.3 (–0.2)  1001-M2010  5–10  11  34  27/27\nM20 × 1.5  EN 60423  20  18.6  20.3 (–0.2)  1001-M2012  6–12  10.5  30  27/24\nM20 × 1.5  EN 60423  20  18.6  20.3 (–0.2)  1001-M2014  10–14  11  34  27/27\nM25 × 1.5  EN 60423  25  23.6  25.3 (–0.2)  1001-M2513  7–13  12  36  33/33\nM25 × 1.5  EN 60423  25  23.6  25.3 (–0.2)  1001-M2514  10–14  11  34  33/27\nM25 × 1.5  EN 60423  25  23.6  25.3 (–0.2)  1001-M2518  13–18  12  36  33/33\nM32 × 1.5  EN 60423  32  30.6  32.3 (–0.2)  1001-M3218  13–18  15  42  41/41\nM32 × 1.5  EN 60423  32  30.6  32.3 (–0.2)  1001-M3225  18–25  15  42  41/41\nM40 × 1.5  EN 60423  40  38.6  40.4 (–0.3)  1001-M4025  18–25  15  46  50/52\nM40 × 1.5  EN 60423  40  38.6  40.4 (–0.3)  1001-M4031  22–31  15  46  50/52\nM50 × 1.5  EN 60423  50  48.6  50.4 (–0.3)  1001-M5028  22–28  16  54  62/62\nM50 × 1.5  EN 60423  50  48.6  50.4 (–0.3)  1001-M5041  31–41  16  54  62/62\nM63 × 1.5  EN 60423  63  61.6  63.4 (–0.3)  1001-M6338  29–38  18  56  75/65\nM63 × 1.5  EN 60423  63  61.6  63.4 (–0.3)  1001-M6345  35–45  18  56  75/65\nM18 × 1.5  DIN 13  18  16.4  18.3 (–0.2)  —  —  —  —  —\nM24 × 1.5  DIN 13  24  22.4  24.3 (–0.2)  —  —  —  —  —\nM30 × 2  DIN 13  30  27.8  30.3 (–0.2)  —  —  —  —  —\nM36 × 2  DIN 13  36  33.8  36.3 (–0.2)  —  —  —  —  —\nM45 × 2  DIN 13  45  42.8  45.4 (–0.3)  —  —  —  —  —\nM56 × 2  DIN 13  56  53.8  56.4 (–0.3)  —  —  —  —  —\nM72 × 2  DIN 13  72  69.8  72.5 (–0.4)  —  —  —  —  —\nM80 × 2  DIN 13  80  77.8  80.5 (–0.4)  —  —  —  —  —\nM105 × 2  DIN 13  105  102.8  105.5 (–0.4)  —  —  —  —  —\nM75 × 1.5  EN 60423  75  73.6  75.4 (–0.3)  —  —  —  —  —\nM90 × 2  EN 60423  90  88.8  90.4 (–0.3)  —  —  —  —  —\nM110 × 2  EN 60423  110  108.8  110.4 (–0.3)  —  —  —  —  —\n\nFiles elsewhere (not hosted by Xem Studio; license as stated by the publisher):\n- Lapp: Technical table T21: thread dimensions for cable glands (metric EN 60423 / DIN 13, PG DIN 40430, NPT), tightening torques and installation dimensions; D1 outer diameter, pitch, D2 core diameter, D3 hole diameter — web — Maker technical table, hosted by a distributor; numbers only — https://www.sos.sk/docs/1/1937/T21 Thread dimensions for cable glands_Tightening torques and installation dimensions for cable glands.pdf\n- VIOX: Cable gland size chart: standard nylon metric series (cable range, thread length, height, key size) and brass PG series — web — Vendor chart; the vendor states hole sizes are for its own series — https://viox.com/fr/cable-gland-size-chart/\n- McMaster-Carr: Cord grips and cable glands (free STEP/IGES per part, for your own design use; no redistribution) — STEP, IGES, PDF — McMaster-Carr site terms: personal design use, no redistribution [verify license at link] — https://www.mcmaster.com/products/cord-grips/\n\nFree files (CC BY 4.0, Xem Studio; STEP + STL, 1 parts): https://xemstudio.com/files/hardware/cable-glands-metric-thread/index.json\nAPI: https://xemstudio.com/api/geometry?object=cable-glands-metric-thread\n",
