Selecting Gage Blocks

Select gage blocks in accordance with the combination range required. If a large length is required, add a long block set.

Select gage blocks in accordance with the minimum length step required. Add wear block sets if necessary.

If a set containing a large number of gage blocks is selected, the number of combination gage blocks required for a length is reduced and the number of combinations is increased. The accuracy will be retained and damage will be reduced.

The specific gage block set for micrometer inspection and caliper inspection is available.

If using only one length repeatedly, it is a good idea to purchase discrete gage blocks.

The 2mm-based gage blocks, which take the base of the minimum length set as 2mm, are easy to handle and will not warp, as compared to the 1mm-based gage blocks.
