ISO 2341 is the standard cited for clevis pins (iso 2341 / din 1444). This page sets out what the standard controls for this part, reproduces the dimensional table supplied against it, and notes the related designations referenced on drawings.
ISO 2341 — Scope
ISO 2341 is "Clevis pins with head".
Tolerance & Product Grades
ISO 2341 does not divide clevis pins (iso 2341 / din 1444) into product grades. Tolerances are given as limits on the individual dimensions in the table.
Where a general-tolerance class is cited on the drawing instead, it applies to the dimensions not otherwise toleranced.
Dimensions Specified by ISO 2341
| Pin diameter d (mm) | Grip length (mm) | Head diameter (mm) | Head height (mm) | Cross hole diameter (mm) | Split pin size | Material | Reference standard |
|---|---|---|---|---|---|---|---|
| 4 | 12 | 7 | 2.5 | 1.6 | 1.6 x 16 | Steel 4.6 / A2 | ISO 2341 |
| 5 | 16 | 9 | 3.0 | 1.6 | 1.6 x 20 | Steel 4.6 / A2 | ISO 2341 |
| 6 | 20 | 10 | 3.5 | 2.0 | 2 x 20 | Steel 4.6 / A2 | ISO 2341 |
| 8 | 25 | 14 | 4.0 | 2.5 | 2.5 x 25 | Steel 4.6 / A2 | ISO 2341 |
| 10 | 32 | 18 | 4.5 | 3.2 | 3.2 x 32 | Steel 4.6 / A2 | ISO 2341 |
| 12 | 40 | 20 | 5.5 | 3.2 | 3.2 x 36 | Steel 4.6 | ISO 2341 |

Companion Standards
ISO 2341 controls the geometry of clevis pins (iso 2341 / din 1444). Surface finish is governed by separate finish standards such as ISO 4042 for electroplating, and corrosion testing by ISO 9227 (neutral salt spray). Mechanical performance is set by the documents specific to this part family — ISO 898-1 and ISO 898-2 apply to bolts, screws, studs and nuts, and not here.
When to Specify ISO 2341
Choose ISO 2341 for international engineering work and OEM supply where ISO standards are the contractual reference. It is the default modern specification for clevis pins (iso 2341 / din 1444).
Custom manufacturing · Made to drawing
Need a pin to this standard in a non-standard size?
Parts built to ISO 2341 are already in the catalog, so a special is usually a variation on existing tooling rather than a new design — which is what keeps the cost down. Made by cold heading or turning.
Minimum order from 2,000 pieces; samples within 7 days of drawing approval.
