Which tool is specifically designed to measure small distances and can provide very fine readings?

Micrometer
Caliper
Gauge
Protractor

The correct answer is: Micrometer

The tool that is specifically designed to measure small distances and can provide very fine readings is the micrometer. This instrument is known for its precision and accuracy, often measuring to the nearest thousandth of an inch (0.001 inch) or even smaller increments. Micrometers work by using a screw mechanism, allowing for much finer measurements than standard measuring tools. This makes them especially useful in applications where precision is crucial, such as in mechanical engineering and machining. Their ability to provide consistent and exact measurements of thin objects like wires or small metal parts makes them indispensable in a millwright's toolkit for tasks that require attention to detail. While calipers also measure distances and can offer fine readings, they are generally less precise than micrometers. Gauges serve specific purposes, such as checking thickness or depth, but are not typically used for precise small measurements. A protractor is designed for measuring angles, which is unrelated to distance measurement, thus making the micrometer the most appropriate choice for this question.
