Rod ends / heim joints DIN ISO 12240-4 series K, 5 to 20 mm: bore, ball width, head diameter, thread, length (male and female) — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/rod-ends-din-iso-12240-4/ (sheet CC BY 4.0) Basis: Maedler K43_803 table, M8 female row checked against Ameco; one series E male (Schaeffler GAR10-DO); McMaster-Carr linked for CAD Catalog version: 2026-10-20 Sizes: see table below - Rod ends (heim joints, ball joint rod ends) are a spherical plain bearing in an eye with a threaded shank: male (a threaded stud, AR / AL) or female (a threaded hole, IR / IL), right-hand or left-hand thread. Series K to DIN ISO 12240-4 is the table used here; the bore tolerance in the source is H7 and the female thread is ISO 6H. - Numbers: Maedler's K43_803 table (nine sizes, 5 to 20 mm). The M8 female row matches Ameco's rod end sheet (bore 8, B 12, C1 9, d2 24, d3 12.5, d4 16, h1 36, l3 16) exactly. The B, C1, d1 and d2 columns are the same on the male and the female type in the source table (asserted); the remaining columns differ and are shown separately as female / male. The letters are the source's and are not interpreted here. G, α and weight columns of the source were not legible and are left out. - A series E male rod end for comparison, Schaeffler GAR10-DO: bore 10, ball width B 9, ball Ø dK 16, head Ø d1 13.2, d2 29, h 48, C1 7, l1 26, l2 62.5, α 12°, thread M10 (single source). - Files: none. A solid needs the eye shape, the shank flats and the thread run-out, which are not in the tables. - Left out: the other rod-end lines (Igus, Misumi), series E tables other than GAR10, the L (left-hand) variants' tolerance, load ratings, chamfers. series K size bore d, mm B, mm C1, mm d1, mm d2, mm female: d3, mm female: d4, mm female: h1, mm female: l, mm male: h, mm male: l, mm thread K 5 5 8 6 7.7 18 9 11 27 10 33 20 M5 K 6 6 9 6.75 8.9 20 10 13 30 12 36 22 M6 K 8 8 12 9 10.4 24 12.5 16 36 16 42 25 M8 K 10 10 14 10.5 12.9 28 15 19 43 20 48 29 M10 K 12 12 16 12 15.4 32 17.5 22 50 22 54 33 M12 K 14 14 19 13.5 16.8 36 20 25 57 25 60 36 M14 K 16 16 21 15 19.3 42 22 27 64 28 66 40 M16 K 18 18 23 16.5 21.8 46 25 31 71 32 72 44 M18x1.5 K 20 20 25 18 24.3 50 27.5 34 77 33 78 47 M20x1.5 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Maedler (Mercateo data sheet K43_803): Rod ends DIN ISO 12240-4 series K, male (AR / AL) and female (IR / IL), d 5 to 20: B, C1, d1, d2, h, l, thread — web — Publisher's page; dimensions are facts — https://static.mercateo.com/c0/e2d28082af85416a8a9b3a6f8a237259/pdf/K43_803_EN.pdf - Ameco: Rod end BR DIN ISO 12240-4 (DIN 648) series K, internal thread M8, right hand: d 8, B 12, C1 9, d2 24, d3 12.5, d4 16, h1 36, l3 16 — web — Publisher's page; dimensions are facts — https://eshop.ameco.cz/products/en/1126/2229/2233/g1688/63240800 - Schaeffler (via Misumi data sheet): GAR10-DO male rod end, DIN ISO 12240-4 dimension series E: d 10, B 9, dK 16, d2 29, h 48, C1 7, l1 26, l2 62.5 — web — Publisher's page; dimensions are facts — https://uk.misumi-ec.com/pdf/ds/INA1/INA1_F0002780235_EN.pdf - McMaster-Carr: Ball joint rod ends (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/ball-joint-rod-ends No true-size file yet: the published figures do not fix the whole shape; a measured scan is planned.
