Dial bore gages are used to measure:

Dial bore gages are used to measure:

• A. Diameters of nuts
• B. Surface finish
• C. Holes
• D. Thickness of plates

Answer: (C)

Dial bore gauges are specifically designed to measure the internal diameters of holes with precision. Their construction allows them to gauge sizes inside cylindrical features, making them essential for ensuring that bore tolerances are met in manufacturing and engineering settings. In contrast, while other options represent measurement capabilities applicable to different tools or methods, they do not align with the primary function of dial bore gauges. For example, measuring the diameter of nuts typically involves different types of calipers or wrenches. Surface finish measurement is generally performed using surface roughness testers rather than bore gauges, and measuring the thickness of plates is more commonly done with calipers or micrometers designed for that purpose. Therefore, the choice that indicates the capability of dial bore gauges accurately pinpoints their specific use, reinforcing the understanding of their function in mechanical applications.
