For trailer owners, the selection of wheel hub components is of paramount importance. It not only affects the overall aesthetic appeal of the vehicle but also directly impacts driving safety performance. The market offers a wide variety of Push Through Center Caps in terms of size, material, and style. However, these center caps are usually sold separately, and the installation often requires Lug Nuts. If your Lug Nuts are lost or you want to modify your wheels, you will need to purchase Lug Nuts separately. At the same time, you may not know what size of Lug Nuts you need.
If you are unsure about the size of the lug nuts your trailer requires, you can refer to the following:
The three most common bolt sizes for trailers are 1/2"-20, 9/16"-18, and 5/8"-18. To ensure you get the correct wheel lug nuts, you now need to measure the wheel studs on your trailer. As a general guideline:
- 1/2"-20 studs are typically used for medium to small-sized trailers.
- 9/16"-18 and 5/8"-18 studs are typically used for larger trailers.
For 3.19" /4.25" Trailers, Trucks, SUVs, and RVs, the center hole requires 1/2"-20 60 Degree lug nuts.
The 1/2"-20 lug nuts are as shown in the image below.
To ensure a secure and proper fit, it is recommended to measure your existing wheel studs and then select the appropriate lug nuts accordingly.
