# Source Tightening Overview

The tightening menu shows a list of Source Batch and Source Tightening configurations. Separate lists can be linked to a Virtual Station by going to the Virtual Station in question, and in the Task properties selecting Choose. There, a Source can be chosen as a task. Source tightenings link a specific tightening program to an identifier number. When the identifier number is sent to the controller, the linked program will run over and over until a different signal is sent .
