Clevis pins with head, ISO 2341 (DIN 1444) forms A and B, d 3–100: head diameter and height, split-pin hole, le, radius + example pin models — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/clevis-pins-iso-2341/ (sheet CC BY 4.0) Basis: Global Fastener's ISO 2341:1986 table for d 3 to 100 (26 sizes), ITA Fasteners' ISO 2341 B table for d 4 to 24 (agrees on every value), Amesweb for what each symbol is, one maker's inch rows (Sunhyings); ten example pin models as files Catalog version: 2026-10-20 Overall (mm): length 18.0, width 18.0, height 54.0 - ISO 2341 covers clevis pins with head, form A (plain) and form B (with a split-pin hole), d 3 to 100 mm. Columns in mm: d (nominal, h11) and its minimum limit, head dk h14 (max / min), head height k js14 (nominal, with its max / min), split-pin hole d1 H13 (nominal / max, B only), c max, e, le min and the under-head radius r. Global Fastener and ITA agree on d, dk, k, d1, c, e, le and r for every size 4 to 24 mm; the tolerance classes (h11, h14, js14, H13) are ITA's and Amesweb's headings, and d min and the max / min values are consistent with them (for example d 10 h11: 9.91 min). - Symbols, from Amesweb's label list: c = end chamfer, e = head chamfer, le = 'end to centre' (the distance from the pin end to the centre of the split-pin hole) and r = under-head radius. The standard says le may in no case be smaller than the tabulated value (Amesweb, iTeh's page for the standard), so le is a minimum, not a fixed position. The sources read give the chamfer sizes c and e but not their angle, so the models leave the end and head chamfers off. - Cotter size follows the hole: d1 is the split pin's nominal size (ISO 1234 split pins are sized by the hole, see split-pins-iso-1234). The size-to-pin ranges of ISO 1234 and the d1 of ISO 2341 line up for every one of the 26 sizes here (for example d 10 and d 12 both take 3.2 mm, d 24 and d 27 take 6.3 mm, d 70 to 100 take 13 mm). - Inch rows (a maker's table citing ISO 2341 B / DIN 1444 and ASME B18.8.1): nominal diameter, its metric equivalent, head diameter, effective grip length range, hole diameter and recommended cotter pin; the page defines grip length as under the head to the centre of the cross hole, and gives h11 as the pin tolerance. One maker's values; the ASME standard was not read. - Files: ten pins drawn at true size from the numbers above (form B at d 4, 5, 6, 8, 10, 12, 16, 20 and form A at d 6 and 10). The shank lengths (20, 25, 30, 40, 50, 60, 80, 100 mm) are Xem's examples; the commercial length series was not read for the full range. The hole axis is placed at le min from the pin end and the hole runs straight through the shank at d1 nominal. Pin ends and head are square (no chamfers). Lengths not listed: change the length in your CAD; the head and hole numbers do not depend on it. - The existing page pins-clevises-and-joints has small model-work clevis pins (d 3 to 8) and a different set of split-pin and R-clip notes; this page is the ISO 2341 table for d 3 to 100. d nominal (mm, h11) d min (mm) head dk h14 max / min head height k js14: nominal (max / min) split-pin hole d1 H13: nominal / max c max e le min r 3 2.94 5 / 4.7 1 (1.125 / 0.875) 0.8 / 0.94 1 0.5 1.6 0.6 4 3.925 6 / 5.7 1 (1.125 / 0.875) 1 / 1.14 1 0.5 2.2 0.6 5 4.925 8 / 7.64 1.6 (1.725 / 1.475) 1.2 / 1.34 2 1 2.9 0.6 6 5.925 10 / 9.64 2 (2.125 / 1.875) 1.6 / 1.74 2 1 3.2 0.6 8 7.91 14 / 13.57 3 (3.125 / 2.875) 2 / 2.14 2 1 3.5 0.6 10 9.91 18 / 17.57 4 (4.15 / 3.85) 3.2 / 3.38 2 1 4.5 0.6 12 11.89 20 / 19.48 4 (4.15 / 3.85) 3.2 / 3.38 3 1.6 5.5 0.6 14 13.89 22 / 21.48 4 (4.15 / 3.85) 4 / 4.18 3 1.6 6 0.6 16 15.89 25 / 24.48 4.5 (4.65 / 4.35) 4 / 4.18 3 1.6 6 0.6 18 17.89 28 / 27.48 5 (5.15 / 4.85) 5 / 5.18 3 1.6 7 1 20 19.87 30 / 29.48 5 (5.15 / 4.85) 5 / 5.18 4 2 8 1 22 21.87 33 / 32.38 5.5 (5.65 / 5.35) 5 / 5.18 4 2 8 1 24 23.87 36 / 35.38 6 (6.15 / 5.85) 6.3 / 6.52 4 2 9 1 27 26.87 40 / 39.38 6 (6.15 / 5.85) 6.3 / 6.52 4 2 9 1 30 29.87 44 / 43.38 8 (8.18 / 7.82) 8 / 8.22 4 2 10 1 33 32.84 47 / 46.38 8 (8.18 / 7.82) 8 / 8.22 4 2 10 1 36 35.84 50 / 49.38 8 (8.18 / 7.82) 8 / 8.22 4 2 10 1 40 39.84 55 / 54.26 8 (8.18 / 7.82) 8 / 8.22 4 2 10 1 45 44.84 60 / 59.26 9 (9.18 / 8.82) 10 / 10.22 4 2 12 1 50 49.84 66 / 65.26 9 (9.18 / 8.82) 10 / 10.22 4 2 12 1 55 54.81 72 / 71.26 11 (11.215 / 10.785) 10 / 10.22 6 3 14 1 60 59.81 78 / 77.26 12 (12.215 / 11.785) 10 / 10.22 6 3 14 1 70 69.81 90 / 89.13 13 (13.215 / 12.785) 13 / 13.27 6 3 16 1 80 79.81 100 / 99.13 13 (13.215 / 12.785) 13 / 13.27 6 3 16 1 90 89.78 110 / 109.13 13 (13.215 / 12.785) 13 / 13.27 6 3 16 1 100 99.78 120 / 119.13 13 (13.215 / 12.785) 13 / 13.27 6 3 16 1 inch: 1/4 in (6 mm) head Ø 0.375 in grip length 0.50–2.00 in hole Ø 0.076 in cotter 1/16 in inch: 5/16 in (8 mm) head Ø 0.438 in grip length 0.75–3.00 in hole Ø 0.106 in cotter 3/32 in inch: 3/8 in (10 mm) head Ø 0.500 in grip length 1.00–4.00 in hole Ø 0.106 in cotter 3/32 in inch: 1/2 in (12 mm) head Ø 0.625 in grip length 1.00–5.00 in hole Ø 0.141 in cotter 1/8 in inch: 5/8 in (16 mm) head Ø 0.812 in grip length 1.50–6.00 in hole Ø 0.141 in cotter 1/8 in inch: 3/4 in (20 mm) head Ø 0.938 in grip length 2.00–8.00 in hole Ø 0.172 in cotter 5/32 in inch: 1 in (25 mm) head Ø 1.250 in grip length 2.50–10.00 in hole Ø 0.203 in cotter 3/16 in Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Global Fastener: ISO 2341:1986 clevis pins with head, types A and B, d 3 to 100: d min, dk max / min, d1, c, e, k, le min, r — web — Reference page; numbers only — https://www.globalfastener.com/standards/detail_252.html - ITA Fasteners: Clevis pins ISO 2341 B: d h11, dk h14, k js14, d1 H13, c max, e, le min, r for d 4 to 24 — web — Maker page; numbers only — https://itafasteners.com/products-pins-clevis.php - Amesweb: Metric clevis pin dimensions: symbol labels d1, dk, dl, c (end chamfer), e (head chamfer), k, le (end to centre), r (underhead radius); d h11, dk h14, dl H13 (calculator; values not readable) — web — Reference page; labels only — https://Amesweb.info/Fasteners/Pins/Clevis_Pins_Dimensions_Metric.aspx - Sunhyings: Industrial clevis pins ISO 2341 B / DIN 1444: inch rows 1/4 to 1 in with head diameter, grip length range, hole and recommended cotter pin (one maker's table) — web — Maker page; numbers only — https://sunhyings.com/?p=10706 - ISO: ISO 2341:1986: Clevis pins with head (standard body catalogue page; the standard itself is paid) — web — Standard body catalogue page — https://www.iso.org/standard/7178.html Free files (CC BY 4.0, Xem Studio; STEP + STL, 10 parts): https://xemstudio.com/files/hardware/clevis-pins-iso-2341/index.json API: https://xemstudio.com/api/geometry?object=clevis-pins-iso-2341
