Check the old reliable - McMaster-Carr. They've got 'em. Its hard to find something they don't have. Any old timers out there are very familiar with their HUGE yellow catalogs - that are almost impossible to get! Modified by Administrator at Thu, Jul 12, 2007, 12:33:21

I'm confused, when I searched Google for "Aluminum Bolts", I got over 2 million results. The first page showed a bunch of promising results. What did you search for? Did you call any if the companies listed?

Well, I searched in a number of suppliers' sites, and usually found that alum. products were not included in their hex bolt inventory. I think the search engin entered them because of the odd rivit or non-ferous screw that they advertized. Anyway, I'm looking for HD alum. hex bolts or coated steel substitutes to bolt my alum. framing together. Any thoughts? Regards, LL

I see at McMaster that the largest AL bolt they carry is a 5/8"-11 thread. Use Stainless Steel bolts. Steel is generally more reliable in the long run for fasteners. On ordinary steel bolts, pretty much any coating will eventually fail and lead to massive corrosion problems, so SS is best. Modified by andrewjmorin at Thu, Jul 12, 2007, 15:57:57

Ya'lls help is very much appreciated! Notably boggs & morins' McMaster-Carr suggestion. The simplist suggestions are often the best! So, (my manuals are still boxed up for building remodeling) I put M&C on my favorites and found many options. Now, I think I'll look for Gr.8 w/ ultra corrosion resist. coating; ( ...still a little nervous about where S/S is on the anodic index scale) then my bolted together hollow panels of aluminum should resist corrsion, wind, and thermal exp/contr. quite well. Thanks again to you all. See 'ya later, Best regards, LL

all-aluminum railcars are built using SS bolts (& rivets). Thus I assure you that it is the best bet to avoid galvanic corrosion for the longest life. Good luck!

Hhmmm, rail cars, huh? Well, that's good to know. As a metal sculptor, I'm committed to producing work that will stand the test of time(at least physically). Thanks , again. LL
