Bought a 5000 lb rated 2" ball and putting it on the receiver insert (not sure what it's called) that is also rated 5000 lbs. Both pieces have a very smooth finish so when tightening it the ball spins. It has flats on it - it's bigger than my wrenches but I can probably figure out something to restrain it. But thinking if it turns that easily and doesn't have much friction if may work loose over time. The bottom has a lock washer under the nut and going for called out 250 ft-lb of torque. Any ideas of what to do to increase the friction on the top side? Or is this a non-issue and I should just tighten it up as is?
