Wheel trim cover removal Four Winds Majestic 27G

We have Dicor simulators on our E450, same stud/nut size as E350. Went with a 1/2" drive deep socket and ratchet. Socket size is 1-1/8" and the ones sold a Lowe's ("Kobalt" Brand) work well. The "hex" part is deep enough to hold the full edges of the stainless jacket over the steel nut. Standard socket can't reach the "hex." I want them tighter than the Dicor tee wrench will get them, and if they rust a little, the Dicor tool won't loosen them.
