WebJul 5, 2024 · Engineering fits are the mechanical structures that transmit loads between fit parts. In a fit, there is a round hole and a round part that fit into this hole. There are … WebFeb 20, 2024 · Tolerances typically come into play when designing fits. In some cases, you might want components to slip easily together, but not have a lot of perceptible play. In other cases, lots of relative movement is okay. You might even need to have two components come together permanently and not come apart. These different cases are called “fits”.
