Which statement about snap gauges is true?

• A. Snap gauges are used primarily in production shops.
• B. Snap gauges are used primarily in research labs.
• C. Snap gauges measure internal threads.
• D. Snap gauges are used to measure depth.

Answer: (A)

Snap gauges are quick go/no-go tools for checking outside dimensions on the shop floor. They’re designed to rapidly verify that a part’s outside size is within the specified tolerance, which makes them ideal for production shops where lots of parts need checking fast. They aren’t used for measuring internal features like threads (that requires thread or plug gauges), nor for measuring depth (which needs a depth gauge or micrometer). So the statement that they’re used primarily in production shops best describes their intended use.
