Highly Accurate Measurements for Manufacturing at the Smallest Scale

The proper functioning of the supply chain involves manufacturing parts with precise dimensions. This precision varies by applications, but high-end mechanical parts sometimes require an accuracy of a few micrometers (just a fraction of the diameter of a human hair). 

NIST provides precision measurement of length for high-value manufacturing industries and scientific research institutions. Calibrated gage blocks ensure that accurate size standards are used in the thousands of manufacturing sites and machine shops throughout the United States. 

Billions of accurate dimensional measurements performed each day guarantee that the parts will fit and operate as intended, regardless of their source.
