Are the copper coated nuts the way to go, or is using regular bolts, double bolting the way. I read something yesterday that said the copper nuts should only be used once...why?? Should I coat the studs with anything?

Those copper nuts are evil.
I throw them away. Who ever had the idea to use them has obvilusly never had a class on the effects of dissimilar metal corrosion. This post has been edited by Jake Raby: Oct 10 2007, 11:19 AM |

Copper plated objects are rated differently than pure copper.
copper plated items are nearly in the same location as steel on the galvanic table and as such are excellent match for stock studs. |
