Just go to Mcmaster-Carr ( http://www.mcmaster.com/ ), type < bolt > into the search field on the top-left corner of the page, it will bring up some drawings of different types bolts (fasteners), click on the < cap screws> icon on the top of the page, and you will be in bolt heaven. They have a really nice user interface. You can select bolt type, bolt properties, dimensions, thread pitch, finish, etc etc. You can get bolts for way under the home depot/ace hardware/sears hardware price ... but you have to buy a box ... Every time I order from them (even at 4pm), I get my order mid-afternoon next day. Super service and great pricing.
There are a couple of good books out there on bolts and fasteners but I've found that the mcmaster site provides better "data". The books talk about fastener types generally; but master gives you the tabular data.
I didn't mention that Alloy Boltz grade 8 stainless bolts come in limited sizes - the largest size is (as I recall) 3/8. So, they don't have a ss arp grade 8 bumper bolt if you wanted one for some reason.
Hope that helps.

I just went overboard and used Grade 8 everywhere I could.

Dacromet: Very familiar with this coating. Personally applied it for years back in the day. It is a dip-spin coating. Excellent for rust prevention. There is an alternate coating available to comply with the RoHS directives. Called Geomet. Same process and very similar results in terms of corrosion protection. Was supprised to see the Dacromet term used. How did the poster come up with this info? Just curious. A main benefit of both these coatings is that fasteners can be processed without worry of hydrogen embrittlement. A big plus when coating washers etc.

I suspect that any bolts purchased from Dr. Rebuild will be 'correct' for restoration, but will not stand up to time any better than the original Chevrolet pieces. If you want a correct restoration then go with the Doc, but any other application would demand a better grade of hardware.
