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.

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.
