There is no single equivalent of “battuta di riscontro”.
In the machining field, “back gauge”, “check plate”, “depth stop”, “stop gauge”, or simply “stop” come to mind, the precise term varying according to type of machine and even the manufacturer. Basically, we are talking about a device/mechanism/component for the precise positioning of a workpiece.

For example, by design, bending machines often have a back gauge; the sheet to be bent is fed in horizontally from the front until it abuts against a rear-mounted stop (ergo "back gauge") positioned to ensure that the sheet is in the correct position ready for the bending operation.
