We used the nylock nuts included in the mounting hardware for these hubs, purchased from AndyMark (http://www.andymark.com/product-p/am-2021.htm). These are the correct nuts from my understanding.

Sorry for our ignorance. We simply did not know that loctite eats away at polycarbonate. We are currently looking at other options.

EDIT: Another thing. The center hubs (6 wheel 1/8" center drop) were not damaged as much as the outside hubs. We have been stress testing our robot by hitting defenses as much as possible.

No ignorance implied, I was simply curious as to what you thought a thread locking substance was going to achieve there.

How much air pressure did you fill your tires to? Did you check the outsides of the hubs as well (take the tire off and really check)? I would be curious if there was any impact directly to the wheel itself that wasn't absorbed by the tire due to a low pressure situation.
