🔍 Key Concepts

• Small hole gauge purpose and what it actually measures • How readings from a transfer measuring tool are commonly checked • Typical use of a micrometer in precision measurement

💭 Think About

• Is a small hole gauge a device that directly gives a reading, or does it just transfer a dimension to another tool? • Which of the choices is normally used to obtain a precise numerical dimension from something you have already sized by feel? • Think about which option is designed for measuring small internal diameters very accurately when used together with another tool.

✅ Before You Answer

• Identify which choice is a precision measuring instrument that reads in thousandths of an inch or hundredths of a millimeter • Eliminate any tools that are mainly for checking flatness, angles, or surface alignment, not internal diameters • Confirm which tool is commonly paired with telescoping or small hole gauges in machining and fitting work
