When installing Stainless hardware to assemble your engine.
If nothing else, do not neglect to use a thread sealer w the stainless hardware. S/S and aluminum dont play well together. that combo is the first and worst about galling. I use real-tuff thread sealant. you can get an 8oz bottle (lifetime supply) just about any plumbing supply, its good to + 550 degrees, Versus a tiny tube of permatex 59214 high temp sealant (auto parts store) is only good to 400 degrees and costs about the same and probably wont be enough to do your whole bolt kit. And when using thread sealant be sure to torque everything to the lower torque values given in the honda workshop manual. lower torque value = lubricated fit, higher = dry fit.
Here is the entire article, I pasted the important stuff below.http://www.fastenal.com/content/feds/pdf/Article%20-%20Galling.pdf
Thread galling is a common, yet seldom understood problem with threaded fasteners. Galling, often referred to as a cold-welding process, can occur when the surfaces of male and female threads are placed under heavy pressure. The frustrating aspect of fastener galling is that galled nuts and bolts may pass all required inspections (threads, material, mechanical, etc.), yet they still fail to function together.
Stainless steel fasteners are particularly susceptible to thread galling, although it also occurs in other alloys that self-generate an oxide surface film, such as aluminum and titanium. During the tightening of the fastener, pressure builds between the contacting thread surfaces and breaks down the protective oxide coatings. With the absence of the oxide coating, the metal high points of the threads are exposed to one another, which increases friction. The combination of these two events can generate enough heat to fuse and seize the nut and bolt together.
Minor galling may cause only slight damage to the thread surface and the installer may still be able to remove the fastener. However, in severe cases galling can completely weld the nut and bolt together and prevent removal of the fastener. If the tightening process is continued once galling begins, the fastener may be twisted off or have its threads stripped.
Unfortunately, even with an understanding of the mechanism of galling, little is known on how to successfully control it. However, galling can be minimized with the following measures:
• Thread lubrication is one of the most effective measures to decrease the potential for galling. The lubricant reduces friction, which is a key element in thread galling. Certain environments preclude the use of some lubricants (such as stainless steel fasteners used in food processing equipment). Also, the operator must be aware that the torque-tension relationship will be altered with the use of lubrication.
