headsets do not have bolts.

if your bearings in your threadless headset are loose and falling all over the place, you need to purchase new bearings, if not a new headset. Have a shop look at it since you dont know what the hell is going on and seem unwilling to read up on the subject.

I also recommend punching the guy you just bought the bike from in the face. He dicked you over.
