A clamp is a device to hold or secure an object, to prevent it from moving. In the United Kingdom and Australia, the term cramp is often used in place of clamp when the tool is for temporary use in positioning components in construction and woodworking; thus a G cramp or a sash cramp but a wheel clamp or a surgical clamp. A vise (or vice in the United Kingdom and some other places) is a mechanical screw apparatus used for holding or clamping a work piece to allow work to be performed on it using other tools, such as saws, planes, drills, mills, screwdrivers, sandpaper, etc. In general, vises have a fixed jaw with another moved in relation to it by the use of the screw.
