	1	+# Dowel pin (ISO 2338 / DIN 7)
	2	+
	3	+Parallel pin of unhardened steel or austenitic stainless steel, d 0.6 to 50 mm, any length, with catalogue sizes as
	4	+presets (4 × 20, 6 × 30, ...).
	5	+
	6	+## Geometry
	7	+
	8	+A cylinder of the nominal diameter **d** and length **l** with the end chamfer **c** on both ends. ISO 2338 gives c
	9	+as an approximate value; it is drawn at 45°. One end face is on the XY plane at the origin, the pin along +Z.
	10	+
	11	+## Parameters
	12	+
	13	+| Parameter | Meaning |
	14	+|---|---|
	15	+| `diameter` | Nominal diameter d, mm (0.6 to 50) |
	16	+| `length` | Length l, mm |
	17	+| `material` | `steel` (unhardened), `stainless-a1` (austenitic stainless) |
