I have Axis rims as well...I upgraded to 20X9 in the front and 20X10 in the rear. The place where I got the rims changed out my bolts all together. I didn't notice this until I got home. They even replaced my locking bolts on all the wheels. I now have all new bolts all around, but I'm going back to them next week to look at the locking bolts they put on. I'm sorry this dosen't help you any, but more so had the same experience you have had.
