Ah misunderstood the context here, I thought it was referring to cleaning up the adhesive after repair. Even still, there are plenty of bolts on a car that if you don’t do the right things to remove them, you can shear them off. Fasteners of all kinds can be broken, if you break them beyond the ability of your tools, the manual is going to tell you to take it to a shop. You can break out the screw extractor from harbor freight, or weld a new head onto the stub. But it’s unlikely the official repair manual is going to suggest that to you.
