NATO Supply Class 5220 is a classification within NATO Supply Group 52, which is dedicated to measuring tools. Specifically, NATO Supply Class 5220 focuses on inspection gages and precision layout tools.

Inspection gages are tools used to measure and verify the dimensions, tolerances, and quality of various objects. They are commonly used in manufacturing and quality control processes to ensure that products meet the required specifications. Inspection gages can include tools such as calipers, micrometers, height gauges, thread gauges, and surface roughness testers.

Precision layout tools, on the other hand, are used to accurately mark and measure the layout of components or features on a workpiece. These tools are essential for ensuring precise alignment and positioning during the manufacturing or assembly process. Examples of precision layout tools include squares, rulers, protractors, marking gauges, and center finders.

By categorizing inspection gages and precision layout tools under NATO Supply Class 5220, it becomes easier for organizations within the NATO alliance to identify and procure these specific types of measuring tools. This classification system helps streamline the procurement process and ensures that the right tools are obtained for various military and industrial applications.
