■ Overview of Gauge Blocks
This product is a "length reference gage (end standard)" used as a reference
dimension, for the calibration of various measuring tools, etc. This product has
two parallel, at measurement surfaces, and it has been accurately machined
so that the distance between the two surfaces should be extremely close to
the nominal size. Additionally, by setting together multiple Gauge Blocks rmly
(called wringing), you can obtain a very precise custom dimension that is the
sum of the dimensions of the wrung Gauge Blocks.
Steel and ceramics, which have high hardness and oer superior wear resis-
tance, are used as the material. The Gauge Blocks are broadly classied as
rectangular or square, based on the shape of their cross sections.

Tips
• Gauge Blocks made of ceramics are referred to as CERA Blocks.
• Rectangular Gauge Blocks of standard size with a nominal size of at least 125 mm
have "coupling holes".
