🔍 Key Concepts

• Notice the note near letter C that reads "1/4 - 20 NC - 2" and think about what kind of feature that designation normally describes on a blueprint. • Recall how internal threads are conventionally drawn in section views versus how a plain drilled hole or a tolerance/fit is indicated. • Compare the pattern of solid and dashed lines inside the circular feature at each letter (A, B, and C) with standard thread symbols in mechanical drawings.

💭 Think About

• What physical feature of a part is usually described by a callout like "diameter – threads per inch – NC – class"? Which choice matches that kind of feature? • Do symbols for hole tolerance, finished diameter, or interference fit typically use special hatching/line patterns inside the hole, or do they rely more on dimensional/tolerance numbers outside the view? • Looking just at the graphic symbol at C (ignoring the text for a moment), which answer choice best matches the idea of many closely spaced alternating lines along the length of a hole?

✅ Before You Answer

• Confirm that you know what "1/4 - 20 NC - 2" specifies (size, thread pitch, series, and class of thread). • Verify in a drafting reference how internal threads are shown in section views and compare that to the symbol at C. • Check whether tolerance, finished diameter, or interference fit would normally be indicated by that kind of sectional line pattern, or by numerical limits and fit designations instead.
