The deformed thread nuts sure didn't HELP anything!

Re: Stainless plus stainless equals problem?
Series 300 stainless for fasteners has a tendency to gall the two pieces together. When you torque the bolt and nut the threads deform,and produce heat. This produces galling in which the two pieces fuse together.
Disimiliar metals, when one is 'softer then the other one' will not produce galling. Electro-corrosion, also called galvantic action, can occur. For the exhaust system bolts this would be a non-issue for me whereas the inability to separate the bolt would be a major problem.
