DIN 1443 Clevis Pins without Head
DIN 1443 clevis pins without head (ISO 2340), shank d 4–90 mm — the headless clevis pin retained between two ears with a cotter through the cross-hole, with the collected h11 shank / H13 hole / chamfer / w ladder per size.

Specifications
A DIN 1443 pin is the clevis pin with the head left off: a parallel h11 shank with a cross-hole for the cotter near the point, retained by the joint geometry itself — it sits in a clevis and is held by a cotter pin passing through both ears and the pin. The collected ladder runs 24 shank sizes, d = 4 to 90 mm, and carries per size: the cotter hole diameter d1 (H13), from 1 mm at the 4 mm pin to 13 mm at the 90 mm pin; the end chamfer c (max); and w, the distance from the pin end to the hole centre (2,2 mm at the small end growing to 16 mm at the large). The reading order at assembly mirrors the headed clevis pin (this catalog's ISO 2341 page): fit the h11 shank to the clevis bores as a running fit, use w to check the cotter hole clears the outer ear's edge once the pin is through the stack, and drive the retainment through d1 — the hole pairs with a metric split cotter pin from the ISO 1234 ladder (see the DIN 94 / ISO 1234 page for sizes and pairing). Because the pin has no head, the joint itself must locate it axially — a retained-between-ears stack or a washer behind the cotter ear; the headed series is the right choice where a single-sided face must take the load. Materials, finishes and shear ratings are not tabulated by the collected specification — per RFQ.
| Standard | DIN 1443 — clevis pins without head; ISO 2340 is the internationally maintained successor designation (source index lists "DIN 1443; ISO 2340") |
|---|---|
| Size range | Shank d 4 – 90 mm, twenty-four sizes in the collected ladder (4–24 in 2 mm steps, then 27–90) |
| Shank tolerance | h11 on the shank diameter — running fit into the clevis bores; drill or ream to nominal, not to a measured pin |
| Cotter hole | d1 (H13): 1 at the 4 mm pin → 13 at the 90 mm pin; pairs with metric split cotter pins per the ISO 1234 ladder |
| Hole position | End chamfer c (max) 1–6 mm; w (end to hole centre) 2,2 → 16 mm — the dimension that must clear the outer ear at assembly |
| Materials / finishes / ratings | Not tabulated by the collected specification — per RFQ (state material, shear load and environment at quotation) |

- Row 6 (12): The source prints the end chamfer at d = 12 as "33" where the surrounding ladder steps 1, 2, 2, 2, 2, …, 3 indicate a decimal-comma value (3,3); reproduced verbatim as printed. Verify against the standard before quoting this cell.
Materials
- Material and finish specified per RFQ — clevis pins take single-shear pivot loads and frequent reassembly; state the working load, clevis width and environment with the order
Ordering & documentation
Documents
Shipments are backed by Mill Test Certificate (MTC), Dimensional Report, Salt Spray Test Report on request, with full batch traceability from raw material to finished product. Quality management follows the owner-confirmed compliance list: ISO 9001:2015, RoHS, REACH. Exact document sets are confirmed on the order.
Quotation
- The fastener family (DIN 1443 Clevis Pins without Head) plus the standard designation from your drawing — DIN / ISO / JIS / ASTM / ANSI, or a drawing for custom parts.
- Size (diameter and length), thread type (metric or inch), property class or grade, and coating or finish.
- Quantity per size and your target delivery date.
- Destination country, and any required documents (for example a mill test certificate) so the quote includes them.
Sample & supply
Minimum order quantities and lead times for this family are confirmed at quotation — send your sizes, grades and quantities on the RFQ and the quote will carry a firm schedule. Sample availability is confirmed with the quotation.
Storage & shipping
Parts are packed for export and shipped factory-direct to buyers in Europe, Asia, the Americas and the Middle East. Store fasteners dry and protected until installation, and keep coated parts in their packaging until use; specific packing and preservation requirements can be stated on the order and confirmed at quotation.
Frequently asked questions
When is a headless DIN 1443 clevis pin the right choice over the headed ISO 2341 pin?
The head on a clevis pin is a single-sided axial stop — it takes the thrust and locates the pin from one face, which is what the headed ISO 2341 / DIN EN 22341 series (this catalog's iso-2341-clevis-pins-metric page) is for. The headless DIN 1443 / ISO 2340 pin is the choice when the geometry has no face to put a head against: the pin passes through both ears (or through a stack capped by a washer on the far side) and the cotter through the cross-hole does the retaining. Sizing order off the collected table: match the h11 shank to the clevis bores as a running fit; check w — 2,2 mm at the 4 mm pin growing to 16 mm at the 90 mm pin — against the stack so the cotter hole lands fully outside the outer ear, not buried in it; and pick the cotter off the d1 column (1 mm hole at the 4 mm pin, 13 mm at the 90 mm pin) using the ISO 1234 pairing on this catalog's DIN 94 page. Two cautions from the collected data: the ladder covers 24 sizes and jumps from 24 to 27 mm — intermediate steps are not covered by published tables, quote them explicitly; and one published cell (end chamfer at d 12, printed "33") carries a transcription quirk flagged under the table — verify against the standard before quoting that cell. Materials, finishes and shear ratings are RFQ lines.
