I would replace them. It’s not that big of a deal and it will give you piece of mind down the road. The “savings” of re-using the bolts is negligible.

And that's perfectly fine. Nothing wrong with that in practice, like I said. We all make our own risk choices.

I've used a tensile testing rig and I know there are sample variations. 'Proven' under my use and anything short of a massive collision or off track excursion and I would generally re-use *any* non-TTY bolt. If the threads are clean and there is no visible sign of deformation, necking or otherwise, and camber settings don't mysteriously go out-of-whack, I'll reuse it.

But a new fastener from the bin...no idea if you happen to get one with a defect. Sure, that's not likely or probable. But in any materials testing, I've found outliers that fail earlier than expected.

Any of these bolts would have a problem staying tight and maintaining the camber setting long before failure. There's a lot of fear about this on the internet along with the TTY misinformation. That's probably not gonna change.

Good advice, on both.

TTY, junk when removed. Bolts with one time use thread locker. Inspect and reuse with locktite after pass.

I have reused suspension bolts too many times to dump after one use. Change a wheel seal and the track bar comes out. Not buying new bolts for that.
