Larry, The stainless capscrews still look new. No heat discoloration or corrosion that I can see. After I read your post, I tried backing one of them out. Came out easily and torqued back down slicker than snot. BTW, I always use anti-sieze compound on any fasteners that get get threaded into aluminum.

No matter what you fix, there will always be something else to fix..
"Warranty" is just another way of postponing the inevitable.
