diagnosis - damaged hub threads - gran compe rear hub

I could use some help diagnosing the condition of the threads on my brand new gran compe rear hub. Bought this hub for my first ever wheel build. Part of the first (outermost) cog thread appears to be damaged. It is rough and jagged in appearance and feel compared to the rest of the threads which are smooth to the touch. Is this normal/negligible or would you recommend returning the hub?

It's fine. Grease the threads and install your cog and lockring (after lacing the wheel, of course).

Installing the cog, which is made of much harder metal than the hub, will essentially chase the threads and make them perfect.

As long as you can get the cog started w/o cross-threading it I woudn't worry. Once you've screwed and unscrewed the cog on loosely a few times to clean the threads it should be ok IMO.
