Quick Attachments
Clamps, cams, and u-shaped washers are used for quick attachments. If a bolt can be pre-tightened during external setup, then it only needs one final turn to provide clamping force during internal setup. Another example to consider is the quick-release hub on a bicycle tire, which facilitates rapid changeover by a lever and cam device so that a wrench and the time that goes with it is not required.
