Buying Guide: Key Purchase Considerations
What axle and hub do you have? Confirm whether your trailer uses Lippert, Dexter, UFP, or another brand. Studs come in different thread pitches, spline diameters, and end head sizes, which must match your hub’s bore and wheel.
What length and spline matter? Longer studs provide deeper engagement but may not fit all wheel studs holes. The 0.54″ spline is common, but some hubs need around 0.61″–0.617″ knurls for a secure fit. Check the thread size (1/2″-20 UNF) and the total length to ensure clearance with the wheel and brake components.
Material and finish influence durability. Galvanized or corrosion-resistant finishes extend life in saltwater use. For boat trailers, choose studs designed for marine environments and exposure to moisture, road salt, and humidity.
Installation notes. Some studs are drive-in type, others are press-in or require nuts. Ensure you have the right tools and follow torque or seating recommendations from your hub manufacturer. Misalignment can cause wheel movement or unsafe detachment.
FAQ
- What is the most common stud size for boat trailers? The common size is 1/2″-20 UNF with about 2.2 inches of overall length and a 0.54 inch to 0.617 inch spline, depending on the hub model.
- Do I need special studs for UFP trailers? Yes, UFP-specific studs are designed to fit UFP hubs and may not fit Lippert or Dexter hubs. Verify compatibility before purchase.
