External Indicating Gage

External indicating gauges are measuring tools used by craftsmen to measure the external dimensions of an object. These gauges are designed to provide accurate and precise measurements of the outer surface of an object.

External indicating gauges typically consist of a measuring head or probe that is placed against the external surface of the object being measured. The gauge then provides a reading or indication of the measurement on a scale or digital display.

These gauges are commonly used in various industries such as manufacturing, engineering, construction, and automotive. They are particularly useful for measuring the diameter, thickness, or length of cylindrical or round objects.

Some common types of external indicating gauges include:

1. Dial Calipers: These gauges have a dial or digital display that shows the measurement. They have two jaws that can be adjusted to measure the external dimensions of an object.

2. Micrometers: Micrometers are precision measuring instruments that provide highly accurate measurements. They consist of a calibrated screw and a spindle that is used to measure the external dimensions of an object.

3. Vernier Calipers: Vernier calipers have a main scale and a sliding vernier scale that allows for precise measurements. They are commonly used for measuring the external dimensions of objects with high accuracy.

4. Depth Gauges: Depth gauges are used to measure the depth or height of an object. They typically have a probe or rod that is inserted into a hole or groove to measure the external dimensions.

These are just a few examples of external indicating gauges used in the supply class Measuring Tools, Craftsmen's in the supply group Measuring Tools. There are many other types and variations available, each with its own specific features and applications.
