A.A Press-in Wheel Studs 1/2″-20 x 1.75
Best for UFP trailers: This press-in stud set is designed specifically for UFP and UFP by Dexter hubs. It is not intended for Dexter, Lippert, or LCI systems. It is commonly found on EZ Loaded and Ranger boats, which often use square-tubed hubs rather than round connections. Choose this if your trailer uses UFP hubs and you need a straightforward press-in replacement that aligns with the hub geometry. A limitation is limited cross-compatibility with non-UFP hubs.
Best for:
- Owners of boats on UFP trailer hubs needing direct compatibility
- Users with common EZ Loaded or Ranger trailer configurations
Caution: Not compatible with Dexter/Lippert/LCI systems; ensure hub brand before ordering.

It’s commonly selected for trailers with mixed Lippert/ Dexter configurations where serrated studs help resist loosening. Best for: trailers requiring a strong, serrated grip and reliable hold.

It’s a clear option for hubs that require a longer engagement, and it comes as a set of 10 for efficient replacement. Best for: trailers needing longer engagement and a straightforward press-in solution. Limitation: Verify spline and head dimensions against your hub to prevent improper seating.
Buying Guide: Key Considerations For Wheel Stud Upgrades
- Identify hub brand and model: UFP, Dexter, Lippert, or other. Stud compatibility hinges on hub design, thread size, and engagement length.
- Thread specifications: Most boat-trailer studs use 1/2″-20 UNF. Confirm the thread and head length to ensure proper seating and wheel retention.
- Stud type: Press-in vs drive-in. Your trailer’s hub will determine which design you need; mis-matched types will not install correctly.
- Length and spline: Ensure the under-head length and spline diameter match your hub’s internal geometry to avoid improper mounting or contact with the brake drum.
- Corrosion resistance: Trailers are exposed to water and road conditions. Choose studs with corrosion-resistant materials and coatings for longer life.
- Quantity and pattern: Sets vary from 6 to 12 studs. For full wheel replacement, a complete set ensures you have spare replacements on hand.
Frequently Asked Questions
- What does “1/2″-20 UNF” mean for wheel studs?
It specifies the thread diameter and pitch (1/2 inch diameter, 20 threads per inch) for mounting wheels on standard trailers. - Are press-in studs compatible with all trailers?
No. Compatibility depends on hub design; some hubs require drive-in or specific lengths and splines. - Can I mix different brands of studs on the same axle?
It’s best to use identical studs on each wheel to ensure even load distribution and retention. - What should I do if the studs don’t seat fully?
Stop and verify hub compatibility, thread engagement, and whether a nut or washer is required by the hub design. - Are these studs corrosion-resistant enough for saltwater trailers?
Look for stainless or coated variants; some brass or zinc-coated studs may corrode faster in salt environments. - Do these kits include nuts?
Some listings include nuts; others are studs only. Always check the product description before purchasing.
