## Questions & Answers

**Q: What is the height on the ball end?**
A: The ball is a regular 2 inch ball. Height depends on the receiver hitch

**Q: ball marks on top says 2 am i missing something**
A: It’s a 2 5/16” ball not a 2”

**Q: Is this a metric thread?**
A: It is not a metric thread.

**Q: Whats the socket size for nut?**
A: The nut on a hitch ball with a 1-1/4 inch shank takes a wrench with a 1-7/8 inch socket. A hitch ball with a 1 inch shank will take a wrench with a 1-1/2 inch socket.
So the best tool for this ball is a 1 1/2” box end wrench.
