About Gauge Blocks
Gauge blocks are suited to the purpose of setting a variety of measuring instruments. Precise measurements are possible as the tools allow for very accurate calibration of micrometers and other measurement tools. They can be used to very accurately measure objects or distances as well.
Typically constructed from high-grade steel or carbides that resist wear and damage. A gauge block is machined to have two perfectly flat sides within minuscule tolerances that are parallel to each other.
Machinists and others who use precision equipment have found many uses for gauge blocks, such as calibrating equipment and measuring devices. Gauge blocks apply for quality control purposes, such as testing machines and machined parts for precision and adherence to tolerance guidelines.
