Gauge Blocks or Slip Gauges as they’re also known, are commonly used when checking the accuracy of an instrument or as a reference when setting a gauge to a specific size.

Read about Gauge Blocks in more detail here.

Steel gauge blocks are commonly used for general purposes and for checking the accuracy of calipers and micrometers.

Tungsten carbide gauge blocks are more commonly used to calibrate instruments and as a reference when calibrating other gauge blocks due to the wear resistance of this material.

Similarly, Ceramic gauge blocks are again commonly used for the purpose of calibration, this material is even harder than Tungsten Carbide and offers the best wear resistance.

We stock Moore & Wright and Bowers gauge blocks in both steel and carbide and can supply ceramic gauge blocks from Mitutoyo.
