**Exact dimensions.** Every file is drawn at true size with no tolerance added. The holes and pins that meet another part are listed below under Mating features, with the fit each joint needs; open those by your process's clearance before making the part.

## Notes

- Columns: pin diameter (= bore d1), outside diameter d2, thickness s. These are the DIN 1440 sizes as sold; the replacement ISO 8738 (DIN EN 28738) uses smaller outside diameters for several sizes (e.g. 12 mm pin: 20 instead of 25), so the two are not interchangeable.
- Pin 7, 24 and sizes above 32 are omitted (single source or conflicting values). Edges drawn sharp.

## Mating features (exact size; open press / slide / run / socket by your process clearance, leave designed and clamp as drawn)

| outer face | Ø d2 (12 mm pin 25, 20 mm pin 32) | split pin (ISO 1234) or R-clip behind it | designed | all |

## Questions

**What washer goes on a 10 mm clevis pin?**

DIN 1440 10: 10 mm bore, 20 mm outside, 2.5 mm thick.

**Is DIN 1440 the same as ISO 8738?**

No. ISO 8738 replaced DIN 1440 with smaller outside diameters for several sizes (12 mm pin: 20 mm instead of 25), so check which one a drawing calls for.
