Definitions:

Transitional Fit

A type of fit in mechanical engineering where parts can either move together freely (clearance fit) or interfere slightly (interference fit), depending on the tolerances.

Maximum Interference

The largest value by which one part exceeds the size of its mating part, making assembly possible only with the application of force.

Force Fit

A type of interference fit where components are pressed together using high force, resulting in a very tight fit with no movement between parts.

Hole
