Get that thing tightened up before you ride it much, if it stays loose like it is, eventually it will wear out the splines and you will need a new hub and axle.
And just a tip, if you don't have a wrench or tool that fits the axle nuts right, don't bother trying to make a pair of channel lock pliers work. I tried that because I couldn't find a 2 inch wrench, and not only was it a pain in the arse, but it also chewed up the nuts very nicely and the nuts came loose even with loctite on them. At harbor freight you can get a friggin huge adjustable wrench (I think it's up to 4 inches or something ridiculous like that) for $18. That's cheaper than those sketchy forked looking things you can get that go on the end of a ratchet or breaker bar, and you don't have to worry about messing up your other tools.
