Torque to YIELD fasteners are not reusable. Yield, by definition, means the part has been permanently deformed. I don't want to get too technical here but it's more than just money making and CYA.

Note that the above image says they only need to be replaced if the bolt shows elongation. So per Mopar, when they were using those style of bolts, they could be re-used if they didn't show elongation.

When I was doing 2.2 or 2.5 head gaskets, depending on my fiscal strength at the time, I would buy a set of new bolts just so I wasn't worried about being short one or two. But when money was tight I would check the bolts before buying any and re-used them. Never had to do the job twice when there wasn't a deck or head issue.

But since these are torque to ANGLE bolts, it's not apples to apples. Unless someone can show me documentation that calls them torque to yield.
