I have a Planet X Hurricane as my winter bike.
It has SRAM Force 22 disc brakes.
I accidently stripped the 6mm allen key hole in the rear thru axle.
Its always been a bit difficult to get the allen key in so I think I must have worn it over time.
I managed to remove the thru axle with a bolt extractor so completed its destruction.

I then set about getting a replacement. Thru axles normally have their spec engraved or printed on them - mine didn't.
Planet X weren't a lot of use.

Anyway I ordered one 173mm long for a 142x12 axle with 1.5mm thread pitch.
I got the pitch wrong - it should have been 1.75mm.
So I ordered a new knurled nut with 1.5mm pitch.
Unfortunately that had the wrong external profile to fit the clamp that holds it to the frame.

I'm now awaiting a new thru axle from eBay - standards eh!!!!

Yeah, it was a concern for me before I bought my first thru-axle bike - experience has subsequently told me they are made of cheese and prone to rounding. Getting a decent set of hex-wrenches has eliminated any further damage (I use Wera Hex Plus) and I also bought a replacement pair (holy crap they are expensive compared to QRs) and I now have a second bike which has the same thru-axles which will help longer term.

I don't know if yours is the same but my thru-axles (Trek Checkpoint) have hex stud holes at either end ~ the front nearside one on mine is starting to round out but since discovering that the other side has the same socket I just use that side instead, you've just got to remember to turn the hex key the opposite way of course.

Are the Wera Hex Plus that good?

Yes. Worth the £40 or so for them, especially if you do a lot of your own maintenance - better than the park tool ones I'd used previously and they are all colour coded so I know the red one is for my thru axles, orange for derailleur bolts and yellow for stem bolts for example.

Definitely worth it though, they engage and fit much better than others I've used. I've started getting other tools they make and they're just as good.
