Stainless bolts

Dano · July 3rd, 2013, 10:42 AM

Ok some of the bolts on my engine are sorta nasty( like corrodes) from the winter it was in my inlaws basement, If I remember from when I had my SV on Ebay they used to sell bolt kits that replaced all the engine case bolts with stainless..different colors and such. Anyone know a link to someone that sells them?

Seems quite expensive for bolts. Have you checked a local hardware store?

Stainless steel bolts are much weaker than any steel bolt used by the manufacturer for the engine.

Stainless steel and cast aluminum don't get along well because they react electrolytically, setting up a small electrical current that results in the thread seizing in the casting.

On top of all, they cannot be fished with a magnet if they fall inside the engine.

When looking for replacement steel bolts, use only 8.8 grade or superior.

"The number in the JIS system means the ultimate tensile strength in kgf/mm^2 divided by 10.

Following is the meaning of the number in the ISO metric system:
The number before the point is the ultimate tensile strength in MPa divided by 100.
The number after the point is 10 times the ratio of tensile yield strength to ultimate tensile strength.

The found JIS and ISO Metric equivalence is as follows:

JIS mark----------------------ISO metric mark
4 or 4T---------------------------4.6~4.8
5 or 5T---------------------------5.6~5.8
6 or 6T------------------------------6.8
7 or 7T------------------------------8.8
8 or 8T------------------------------8.8
10 or 10T--------------------------10.9

I'd just use normal bolts and spray your metal with ACF50, I live where it rains all winter and it's constantly salty as I am never more than a quarter of a mile from the sea.

I have no corrosion and my bike lives outside 24/7

Aluminum is not going to be as strong as stainless or ferrous.

If you know your sizes these will be much cheaper. You can order by piece.
