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. ## Frequently Bought Together - CURT 40039 Chrome Trailer Hitch Ball, 12,000 lbs, 2-5/16-Inch Diameter, 1 x 2-1/4-Inch Shank - Trailer Tug - 3,500lb Tongue Weight Trailer Mover for RV Boat Motorcycle Jetski- World's Greatest Trailer Dolly - CURT 40004 Chrome Trailer Hitch Ball, 6,000 lbs, 2-Inch Diameter, 1 x 2-1/8-Inch Shank --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.pa/products/18375874-curt-manufacturing-40039-2-5-16-in-diameter-chrome-trailer](https://www.desertcart.com.pa/products/18375874-curt-manufacturing-40039-2-5-16-in-diameter-chrome-trailer) --- *Product available on Desertcart Panama* *Store origin: PA* *Last updated: 2026-10-02*
