This ball is great the only downside is that the nut and the washer are not stainless. The review above me stated that the yellow tab did not stop the ball from turning, it is meant only for show. The yellow tab is removed prior to installation. NOTE: In order to use the one wrench torque you must have a Master Lock ball mount which has a metal pin to lock into the groove you see in the picture.
This polished stainless steel trailer hitch ball does cost more than the traditional plated steel balls. After years and years of rusty trailer hitch balls you have to put grease on this is over for good. The quality of the ball is outstanding and easy to install. I still had to use another wrench to put the final torque on the ball. The yellow tab thing didn't work to stop the ball from turning. No issue as the ball is the last I will ever have to buy.
