I'm just getting back to an RV-12 empennage kit that I started in 2010 and had to box up in 2012 due to life getting in the way. Unpacked these bolts (still in the paper bags) for the next build step, and saw what appears to be surface damage. Since it's been so long since I was last working on the plane I can't recall what condition the bolts were in when I received them.
First, let me be clear that I'm planning to order replacements for these bolts. Cheap piece of mind.
However, I'd like some advice on:
1) What are the limits for acceptability in hardware condition. Are scratches and chipping of the plating acceptable?
2) Does the marking on these bolts indicate corrosion?
and more fundamentally,
3) Do I need to be concerned about all the other fasteners in my kit, beyond typical inspection prior to installation, including rivets already installed? I'm hoping not.
Thanks,
Alex
