Description: |
| This set of calipers is designed for measuring shafts. It uses a double-screw to set the distance.
Since the calipers here have a very limited range of adjustablility and are not designed to be quickly adjusted, they are more akin to an ajdustable go/no-go gage than a traditional calipers. |
