Observe and Identify Rounded Bolts

What happens here

The video begins by illustrating the common problem of a rounded-off bolt. The presenter first attempts to turn the bolt with a standard tool, demonstrating the 'rounding over' sound and lack of grip. A close-up view then clearly shows how the corners of the bolt head are completely worn away, rendering it impossible to remove with conventional wrenches or sockets. This visual demonstration underscores the need for a specialized tool.
