After 6 months, I'm finding the chassis screws are getting stuck in the 2-D mounts from corrosion or galling between the aluminum mounts and the steel (I guess) screws. :--------------------------------------------------------------- Hi Bob, As I understand it in certain climates there is a problem with electrolytic corrosion between disimilar metals, with some combinations worse than others. For use in my motorcycles the use of Copperslip or some similar anti-seize compound is essential for this purpose. Also use this for stainless to stainless steel bolts/nuts to prevent what you termed as galling. Had a near disaster with this very subject about five years back where our work airstrip Southern Avionics non directional beacon antenna was damaged in a violent sandstorm. The technicians decided to impress me by getting the new antenna assembled before I arrived on site. Alas they had assembled the upper loading coil part of it upside down and try as we might the bolts on stainless steel straps retaining the loading coils would not come apart. Eventually after some hours work managed to loosen the straps enough to get it assembled correctly. This was a warning to me at least of the problems that can arise with stainless steel bolts. All it needs is a little oil, grease or preferably anti-seize compound on assembly to prevent the problem.
