Rallye wheel center cap screw mount holes

Fyi, stainless into aluminum is a problem. Use anti-sieze or as mentioned earlier locktite. This prevents galling. Maybe not such a problem with coarse thread, but fine thread for sure will lock solid.

I recently ran into this issue replacing spark plugs in wifes 2011 RAV4 2.5 ltr. 4 cyl.. Lucky me did have the metric tap to clean up one bolt hole that held their coil pack/plug wire in place. I dont know what plating they put on the bolts but all of them got some anti-seize going back.
