Clevis pins ISO 2341 B, Ø3 to Ø8 — dimension sheet Source: Xem Studio, https://xemstudio.com/objects/clevis-pins/ (CC BY 4.0) Basis: ISO 2341 form B clevis pin: head Ø and height, split-pin hole Ø and its axis distance from the shank end Catalog version: 2026-10-20 Sizes: see table below - A plain shank with a head on one end and a cross-hole for a split pin near the other. The shank length L is measured under the head, so each file is L plus the head height overall (Ø3 × 12 is 13 long, Ø8 × 40 is 43). - Head Ø × height, cross-hole Ø and hole axis from the shank end, by pin Ø: 3 → 5 × 1, 0.8, 1.6; 4 → 6 × 1, 1.0, 2.2; 5 → 8 × 1.6, 1.2, 2.9; 6 → 10 × 2, 1.6, 3.2; 8 → 14 × 3, 2.0, 3.5. - The shank is drawn at the pin Ø exactly. The holes it passes through on a clevis or link are drawn at the same Ø; which joints turn on the pin and which hold it fixed is listed under Mating features. - The cross-hole takes an ISO 1234 split pin of the same nominal size (0.8 hole, 0.8 split pin). The R-clips in this library have a 1.2 wire, which passes the Ø1.2, Ø1.6 and Ø2.0 cross-holes of the Ø5, Ø6 and Ø8 pins. pin Ø length L overall head Ø × height cross-hole Ø hole axis from end 3 12 13 5 × 1 0.8 1.6 3 20 21 5 × 1 0.8 1.6 4 20 21 6 × 1 1.0 2.2 5 20 21.6 8 × 1.6 1.2 2.9 5 30 31.6 8 × 1.6 1.2 2.9 6 30 32 10 × 2 1.6 3.2 8 40 43 14 × 3 2.0 3.5 Files elsewhere (not hosted by Xem Studio; license as stated by the publisher): - Wikipedia: Clevis fastener — web — CC BY-SA 4.0 (text) — https://en.wikipedia.org/wiki/Clevis_fastener - Wikipedia: Universal joint — web — CC BY-SA 4.0 (text) — https://en.wikipedia.org/wiki/Universal_joint - Wikipedia: Rod end bearing — web — CC BY-SA 4.0 (text) — https://en.wikipedia.org/wiki/Rod_end_bearing - McMaster-Carr: Clevis pins (free STEP per part, for your own design use; no redistribution) — STEP, PDF — McMaster-Carr site terms [verify license at link] — https://www.mcmaster.com/products/clevis-pins/ - McMaster-Carr: Rod ends (free STEP per part, for your own design use; no redistribution) — STEP, PDF — McMaster-Carr site terms [verify license at link] — https://www.mcmaster.com/products/ball-joint-rod-ends/ - Long Earth Society: Engine and rig builds — web, video — LES site — https://longearthsociety.com/engineering/ Free files (CC BY 4.0, Xem Studio; STEP + STL, 7 parts): https://xemstudio.com/files/hardware/clevis-pins/index.json API: https://xemstudio.com/api/geometry?object=clevis-pins
