ISO 2341 Clevis Pins (Metric)
ISO 2341 clevis pins, metric shank 3 – 100 mm — the single-shear hinge pin with a low flat head, cotter hole and chamfered point in the metric series, with the collected per-size table: head, hole, chamfer, head height and length geometry.
Last updated: 2026-11
Specifications
The metric clevis pin is the same hinge-in-a-part as its inch counterpart — low flat head, cross-hole for the retaining clip or cotter near the point, chamfered end that finds the hole — but sized on the metric ladder, where the collected table runs from a 3 mm shank (a 5 mm head, 0.8 mm cotter hole, 6 mm nominal length: linkages in small mechanisms and appliances) to 100 mm (a 120 mm head, 13 mm hole, 200 mm nominal: heavy linkages, agricultural and construction pivots). Per size the table carries: shank diameter d, head diameter dk, cotter hole diameter dl, end chamfer c, head chamfer e, head height k, end-to-center distance le (head face to the cotter hole center — the dimension that positions the retainment relative to the clevis ear), underhead radius r, and the length envelope nom/min/max (a ± 0.25–0.75 mm manufacturing band around nominal, e.g. 99.25–100.75 at the 100 mm pin). The reading order at assembly matches the inch pin: fit the shank to the clevis bore, check that le puts the cotter hole clear of the ear's edge, and drive the retainment through dl — pair the hole with a metric split cotter pin from the ISO 1234 ladder (this catalog's DIN 94/ISO 1234 page carries the pairing column). Shank sizes 6, 16 and 25–32 mm are not covered by published tables (see the table footnote). Materials, finishes and shear ratings are not tabulated by the collected specification — per RFQ.
| Standard | ISO 2341 — clevis pins with head, metric series (low flat head, cotter cross-hole, chamfered point for single-shear pivot duty) |
|---|---|
| Size range | Shank 3 – 100 mm, twenty distinct sizes; sizes 6, 16 and 25–32 mm are not covered by published tables |
| Tabulated geometry | Per size: shank dia. d, head dia. dk, hole dia. dl, end chamfer c, head chamfer e, head height k, end-to-center le, underhead radius r, length nom/min/max — e.g. 12 mm: dk 20, dl 3.2, k 4, le 5.5, length 24 nominal (23.5–24.5) |
| Length envelope | Nominal ± 0.25 at small sizes widening to ± 0.75 at 45 mm and up — a manufactured band around nominal, not a cut-to-length dimension; other lengths per RFQ |
| Retainment | Cotter hole dl: 0.8 at the 3 mm pin → 13 at the 100 mm pin — pairs with metric split cotter pins per the ISO 1234 ladder (see the DIN 94/ISO 1234 page for sizes and pairing) |

- Row 1 (4): Values agree with the first table on every overlapping size (4–14, 18–24); the 6 and 16 rows are new — they were absent from that table. Shank 25–32 are not tabulated anywhere — the size range above 24 remains open.

Frequently asked questions
How do I pick the ISO 2341 size, length and retainment for a metric clevis?
Three readings off the collected table, in order. First the shank: match d to the clevis bores — the pin is a running fit, so drill or ream the bores to the nominal, not to a measured pin. Second the length: the nom/min/max band (± 0.25 at small sizes, ± 0.75 from 45 mm up) is the manufactured envelope around nominal, sized for a standard clevis without spacers; if your stack-up includes washers or spacers, order length as clevis width plus stack plus enough protrusion that the cotter hole sits fully outside the ear — use le to check that geometry, since it places the hole center relative to the head face. Third the retainment: the dl column is the hole the cotter passes through — 3.2 at a 12 mm pin, 13 at 100 mm — and the ISO 1234 pairing on this catalog's DIN 94/ISO 1234 page names the cotter size per pin. One size caution: shank sizes 6, 16 and 25–32 mm are not covered by published tables — quote them explicitly and they will be confirmed at RFQ rather than interpolated. And as with the inch pin, none of this table carries load ratings: shear capacity, material and finish are RFQ lines.
