whats weird is M8 fine is used for lots of head bolts and such, so everyne has thread inserts and repair kits. I spose if the normal use for that size is that sort of thing then finding stainless is pretty unlikely.

"Location: Somewhere between Chicago and Milwaukee..."

There's gotta be 50 Fastenal's within 10 miles of that location. I've got three by me and maybe 15 Ace Hardware's of varying complexity along with a half dozen old time local hardware stores that have survived the invasion of Wal-Mart/Home depot. They all have stainless steel metric fasteners stuffed in those little beige boxes all neatly stacked on top of one another, some stores have a more complete inventories than other.

But the Fastenal's are by far the best deal the price there for a pack of 50 or 100 something like a M8Xx-length is about the same as a half dozen at Ace. I try to partronize them all because the good managers who know their stock can often steer you onto a solution. You gotta get out and see what's in the neighborhood. Your in the machine shop of the world.... or used to be

I was unaware fastenal had stores. Seriously. Ive been using grainger and crap like that all my life. I shall have to look and see. Trust me I know I am in the machine shp of the world. I used to BE part of the machine shop of the world. I branched off into electronics, then computers, and by a weird twist f fate now IM an electronic tech for the government. I used to make machine controls and safety controls FOR ITW and Fastenol. I actually worked for a week in the Harley factory in York. Its just been a long time since I was much of a machine shop do-it-yourselfer.

There is a fastenal store 3.6 miles from me. He will be my new best friend.

Yes they will cause once you get to know them they sometimes open a bag og bolts and hand you what you need and smile when you ask how much and then say have a nice day. I've gotten bunches of free nuts, bolts, screws from them but always make sure to occasionally buy bigger ticket items to keep everyone happy.

All the screws holding the plastic lights and trim and things like that will last forever if you make them stainless.
Stainless galls and will seize. Use anti-sieze to prevent that.

Be aware that you might just be moving the corrosion from the bolt to the thing that the bolt threads into. Galvanic corrosion occurs when dissimilar metals are in contact and an electrolyte (rain water, road spray, etc.) is present. The metal further down the pecking order corrodes.

Have you tried Amazon.com? They have an assortment of vendors with a good selection of just about everything. I found some Vendors with a decent price on nutserts at quantities I can handle. My favorite part is they have their own credit card registration that handles the payoff for any purchace from Amazon. Search it out, and give it a try.

Very emphatic +1 on relocating the corrosion to the parts being fastened together.

Galling should not be a problem between a stainless screw and an aluminum casting, but anti-sieze is really a must on stainless nut and bolt pairs; particularly smaller diameter sets because they are so easy to over-torque. And, the likelyhood of galling increases very significantly if stainless nut and bolt pairs are exposed to heat, particularly from exhaust components.

The Nutty Company seems like an excellent source. The ony thing is paying that shipping charge anytime you want to change out hardware. That goes for any web order outfit as well. All in all, the best choice would probably be the yellow pages, calling every hardware store for 20 miles or so till you find someone who has the variety of fasteners that you need.

I've seen threads eaten away in aluminum castings after some years of having stainless steel bolts in them.

That's a stainless steel screw in an aluminum plate.

I can't say one way or another, but others have reported that problem: http://www.finishing.com/310/20.shtml

The other reason to use anti-sieze, liberally, between aluminum and stainless is that it forms an air-tight barrier that prevents the entry of electrolytic liquids (rain water with pollutants, road spray, saltwater, etc.) that would accelerate the galvanic corrosion process.

Yeah I know about the stainless-aluminum thing. I don't think for the purposes I'm using them, this should be a problem. There's not a lot of aluminum on the bike besides the engine, and those obviously wont be stainless. I'm mainly trying to replace all of the cap screw/nylock combinations, and anti-seize will be used heavily both to prevent galling and keep out moisture in general. From what I'm reading, Stainless screws into mild steel and low alloy should be fine as long as the steel in question is much larger, which in these cases it will be (sidecar tub mostly), and threadlock will be used to keep out water there as well. I do appreciate every one's input though. Its nice to have a team of knowledgeable people telling me everything I'm doing wrong shortly after I do it. =8D

That sounds reasonable to me. You might consider using galvanized washers in places where their appearance won't be an issue. That's your sacrificial anode which will take the corrosion.

You're supposed to ask us before you start the project. Then we can argue amongst ourselves for weeks on end while you are in limbo waiting for some kind of consensus to develop before you move forward.

Although I mostly use a copper-based anti-seize, let me recommend this stuff for the stainless-aluminum fastening. It's called Tef-Gel, and is available from almost any marine supply store, since stainless + aluminum + salt water = instant crud.

It's available in everything from 1 ounce tubes to 40# pails.

I brought this up before in reference to stainless screws on the carbs, and someone commented that the metal used for the carbs is actually an aluminum alloy. Can't remember the name of the alloy, but it has a specific name. It is less susceptible to galvanic action because of the admixture of metals in it.
