HobbydexWashers and shims
Washers, shims and spacers share one spec: bore, outer diameter and thickness in mm. The generic name follows the thickness, whatever the maker calls its own part; countersunk and conical ones carry a prefix.
| Thickness | Name |
|---|---|
| under 1 mm | shim |
| 1 mm to under 3 mm | washer |
| 3 mm and up | spacer |
