Tool marks on a new hub axle
Recently bought a Bitex BX103R hub due to endless troubles with previous ones.
Now discovered that it has a single tool mark/pit somewhere around the main hub bearings or closer to the centre as far as I can remember. Will have to take a picture sometime. Looks like something as a result of mishandling.
Since it looks fairly shallow and not overly sharp then I'm not sure if there should be any concern about stress risers/concentration?
Got too many other things going on so sending it back for inspection seems like a too much trouble at the moment.

It's a shallow mark on aluminium or stainless steel (non-magnetic) axle without any sharp angles as far as I can remember. Somewhere it was advertised as steel axle though.

2) Your hubs have cartridge bearings, which will likely go many thousands of miles (or even tens of thousands of miles) without needing service.
3) Most people don't lube cartridge bearings. Just replace them.
And...
4) Your hub is probably just fine.

Why hasn't the OP already completed the repair, so they can be cycling instead ranting on this thread that will not provide any help at all?
Do they require the support of strangers here to agree, so they can print it all out on hardcopy and provide it as "evidence" to the supplier of the new part?

Discovered there is some knocking in the bearings. Probably due to threaded endcaps being finger tight only (without using allen keys) so decided to take it apart again.

Not sure what exactly I'm looking at. Almost looks like a chip in some paint.

From what I read that hub has several interchangeable "axles" available so you can easily swap the wheel onto different OLD bikes? Someone that actually sells or services these things can explain. Looks like a paint chip to me.

Can't see any paint there. With paint chip there wouldn't be an uneven surface.

What I see in the single photo you posted looks more like a paint chip than just about anything I've seen. But like I said, I'm not exactly sure what it is I'm looking at--or maybe what you really want us to see. Maybe zoom out a little?
