#### 1.1.5 Mechanical Joint: Press Fit

Press fits, or interference fits, involve an inner component, such as a shaft, forced into an undersized hole. Once assembled, the parts are held together by the friction of the press fit. Press fits require machining to tight tolerances and precise, accurate placement at high force, typically with a hydraulic press.
