ISO 2340 Clevis Pins Without Head
ISO 2340 headless clevis pins — d h11 4 to 90 with cotter hole d1 H13, the plain-ended pin retained by a cotter in fork (clevis) joints, with the collected d1/c/w rows across both source panels.

Specifications
ISO 2340 is the headless half of the clevis-pin pair: where the ISO 2341 pin (metric clevis page in this catalog) carries a head that locates against one fork eye, this pin is a plain cylinder through and through — retained on both ends by split cotter pins through the cross-drilled d1 hole, sitting flush inside the clevis fork. That makes it the choice for enclosed linkages, rotating fork joints, and anywhere a protruding head would foul. The collected ladder covers d h11 from 4 to 90 across the source's two panels, with per-diameter cotter-hole diameter d1 H13 (1 mm at d4 up to 13 mm at d80/90), chamfer c max and the cotter-hole centre distance w from the pin end (2,2 mm at d4 up to 16 mm at the large end). Order by pin diameter; the cotter itself comes from the DIN 94 split-pin page in this catalog — note the pairing: the d1 H13 hole is sized for the cotter's shank. One verbatim source defect is flagged and not normalized: c max prints 33 at d = 12 against the ladder's 2/2/3 progression — read that cell per RFQ if the chamfer matters. Material and finish are not tabulated by the collected specification — per RFQ (clevis pins in machinery are commonly hardened steel or stainless; confirm at quotation).
| Standard | ISO 2340 — clevis pins without head |
|---|---|
| Size range | d h11: 4 – 90 (two source panels: 4–24 and 27–90) |
| Cotter hole | d1 H13: 1 (d4) → 13 (d80/90) mm, cross-drilled for a split cotter |
| Chamfer | c max: 1 – 6 mm per size (d12 cell flagged verbatim) |
| Hole position | w (cotter-hole centre to pin end): 2,2 – 16 mm per size |
| Material / finish | Not tabulated by the collected specification — per RFQ |

- Row 2 (c max.): d = 12: the source prints c max. 33 against the ladder's 2 / 2 / 3 progression (likely a lost decimal comma). Carried verbatim, not normalized.

Materials
- Material and finish specified per RFQ — state the joint duty (rotating, static load, outdoor) at quotation; the mating cotter is DIN 94 per this catalog
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 (ISO 2340 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
Headless (ISO 2340) or headed (ISO 2341) clevis pin — which does my fork joint need?
End-play handling and enclosure. The headed ISO 2341 pin locates against one fork eye with its head, so it is faster to fit and cannot slide out — the standard choice for open linkages and quick-release yokes. The headless ISO 2340 pin needs a cotter at both ends (one through each fork eye side), which buys two things the headed pin cannot: the pin stays fully inside the fork envelope (nothing protrudes to foul a guard, chain or adjacent part), and axial play can be shimmed or adjusted cotter by cotter on both sides. The collected ladders make them near-companions in geometry — the d ranges overlap and both carry an H13-class cotter hole — so the real decision is spatial. Note the pairing discipline: the cotter itself is a DIN 94 split pin sized to the d1 hole, and the one flagged cell (c max 33 at d12, verbatim print) plus pin material and finish all stay per RFQ.
