🔍 Key Concepts

• Carefully read how each diameter is toleranced (e.g., +0.003 / -0.003 versus +0.000 / -0.003). • Identify every diameter on the drawing (9/16, 5/8, 33/64, threaded end) and determine each one’s maximum possible size using its tolerance. • Remember that the nominal size is not always the largest size; the largest size is nominal plus any positive tolerance.

💭 Think About

• For each labeled diameter, what is the numerical value in inches of its maximum possible size once you apply the given tolerance? • Which diameter on the drawing ends up with the largest upper limit when you add the positive tolerance (if any) to the nominal dimension? • Is there any place where the tolerance is +0.000 / -0.003? If so, what does that mean for the maximum allowable size of that feature?

✅ Before You Answer

• Double-check each diameter’s tolerance block and write the upper limit (max size) next to it in decimal inches. • Be sure you convert all fractions to decimals (like 9/16, 5/8, 33/64) before comparing sizes. • Confirm that you are comparing maximum (upper-limit) diameters only, not minimum or nominal, before matching to the answer choices.
