If I'm wrong and there are threaded holes that get buggered up in more permanent parts, Heli-CoilŪ to the rescue.
Really, I'm struggling to understand why these bolts are considered to be a big deal.

Your logic appears to be:
* Damaged parts should be re-used until they totally fail, requiring additional time, money, and/or energy to repair.
Sorry, that defies both Logic and Common Sense..
Engine mounts are safety = Heli-CoilŪ repair should be the LAST resort, it can fail the wrong way during a traffic impact, possibly killing you or others...
Example of repair:
W123 and W126 engine mount
If the two small upper Allen cap screws are damaged/rounded, the mount will NOT come off the frame!!!
If the large lower Allen cap screw is damaged/rounded, the engine will not separate from the mount!!!
If the inner upper and the lower cap screw are damaged:
* You must raise and support the vehicle high enough for drill access underneath
* Drill the head off the lower bolt
* Raise and support the engine
* Drill, saw, or grind out the upper bolt head, (any V8 is seriously difficult to access)
* Remove the mount
* Extract the threaded stubs
* Replace the engine mount
* Replace the destroyed cap screws with NEW
This repair could have been avoided by replacing six damaged fasteners..
