Anything is possible. However, i doubt that. My box was perfectly intact. The threads appeared perfect upon arrival and initial install.
What is odd to me is that only the threads on the top of the axel are getting ruined. (having your phase wires exit out the bottom of your dropout should help determine the "top" and "bottom" im talking about). I've turned my share of bolts in my lifetime. Ive never seen any situation (other that this) where only 1/2 the threads on the same bolt peel off. And for this exact scenario to happen to both me AND wojtek...?

Axle Threads Poorly Machined, Stripped
We always tell people to really do the axle nuts up as tight as possible to prevent axle spinout. However, Crystalyte turns the threads on a lathe rather than with a die and sometimes the tolerances are off. The nuts can be hard to spin on, or they can be so loose that the threads strip when the nut is tightened.
Sounds like exactly what happened to me. I wasnt even close to being snug when it just kept spinning without moving. I started with my vulgor expletives and removed the hub (knowing it was useless without repair) and re-installed the 5304. Used the SAME hardware (however dumb it was) on the 5304 and it worked fine. So that rules out the nut being the cause of damage to the axle. And even if the nut was bad, the axle should ruin the nut, NOT the nut ruins the axle!!
