Which statement best describes a clearance fit?

• A. A fit with no clearance and requires force to assemble.
• B. A fit with a small gap between parts at assembly.
• C. A fit designed to be pressed together.
• D. A fit that allows exact zero clearance when assembled.

Answer: (B)

Clearance fit means there is always some space between the mating parts after they’re assembled. The bore or hole is larger than the shaft, so you can put the pieces together without forcing them and they can still move a little relative to each other. The description of a small gap at assembly matches this idea perfectly—there’s intentional play that allows easy assembly and relative motion.

In contrast, parts that require force to assemble describe an interference (or press) fit, where there is no room to fit without deformation. A zero-clearance statement implies no space at all, which isn’t a clearance fit. A fit designed to be pressed together also points to interference.
