Dimensional inspection uses which set of tools?

• A. Micrometers, T-gauges, feeler gauges, go/no-go gauges, and dial indicators
• B. Ultrasonic
• C. X-ray
• D. Magnaflux

Answer: (A)

Dimensional inspection focuses on verifying actual part size and geometry against the drawing using direct-contact measuring tools. The best-fit toolkit for this purpose includes micrometers for precise external dimensions, T-gauges and feeler gauges for small clearances, go/no-go gauges to quickly confirm whether a feature stays within tolerance, and dial indicators to detect deviations and runout against a reference. These tools allow you to compare measurements to specified tolerances and identify any out-of-spec parts. By contrast, ultrasonic testing, X-ray, and Magnaflux are nondestructive methods aimed at finding internal flaws or assessing material integrity, not measuring dimensions.
