I use it to eliminate backlash when adding bearings to fishing reel. I added a bearing to the handle of Abu, but since there was a backlash, I adjusted with this shim. It is a good shim for rust.
I bought it for my hobby. Whether you use the model with punching, there was bulging and burrs and it was not possible to adjust exactly. Although the price is a little expensive, the Iwata Seisakusho's shim is clean, 0.1 mm, 0.2 mm, 0.3 mm and can be adjusted efficiently.
Accuracy of inner diameter / outer diameter / thickness was also reasonable, and it was too much for use in places that require less accuracy. Compared with the imported goods of the radio control maker (made in ○ country), I am impressed with the goodness of accuracy.
