Avoid any thoughts about chromed or stainless hardware.

I have been unable to find any really good stainless bolts, seems like they are all soft, low-quality parts. Chromed parts, unless they have been baked post-plating, will have free hydrogen atoms in their makeup. These atoms act like little chisels and can break or crack a fastener, even if it is under NO load, and since you have no idea if the fasteners were baked or not, sidestep chromed hardware or any hardware that has been electrolytically plated. Read up on "hydrogen embrittlement" if you want to add to your knowledge.

Here's a quick chart showing "hash marks" and corresponding strengths....

As far as a scattershield is concerned, please read through this thread.....
