IMO the stock chinese hardware is best and most problems are caused by noobs not knowing when to stop torquing. A stubby ratchet handle is your friend.
I'm thinking you haven't examined the threads on the nuts very closely...
The stock studs can be "o.k." but a lot of the nuts are absolute junk.
I do agree that a "stubby" ratchet (and some blue loctite) are better than the gorilla technique for tightening all fasteners.
