Good eye! The machine screws on our new hitch balls are part of our secure connection process.
When inserting the hitch ball into your coupler, turn the screws to the 10 o'clock position in order to keep the ball from spinning inside the coupler while operating the dolly.
In some cases, the machine screws can be removed. This is needed to connect to surge brake actuators (such as Dexter Dx7.5). If you are unsure about whether the machine screws are necessary for your trailer connection, you can contact our sales team.
