Brand New Turbo Question (with picture)

[jspaeth]

Okay....so my GT2871R just came in the mail from ATP, in a Garrett box, brand new!

I am excited, and I was looking at it and all, and I found a possible problem, but I need some experts to chime in.

The picture below shows the end bolt holding the compressor wheel in place:




My concern is over the bolt holding the compressor wheel on.....if you look carefully, it looks like the one side of the bolt, on the bottom left side, (which should be hexagonal) is kind of rounded off....

I am wondering if this should be cause for concern....with the turbo rotating at 100,000 RPM+, proper rotational balance is EXTREMELY important, and I am wondering if the bolt being rounded on the one corner is enough to create problems


Thanks
