The three most common lug stud sizes for a trailer are 1/2"-20, 9/16"-18, and 5/8"-18. In order to make sure you get the correct lug nuts you need to measure the lug studs on the trailer now as we have no way to look this up for individual trailers. I have attached a few options based on the lug stud size below. The 1/2"-20 studs are used on small-medium duty trailers whereas the 9/16"-18 and 5/8"-18 lug studs are used on larger duty trailers.

Chrome Trailer Wheel Lug Nut 1/2"-20 Closed Short part # 12CLN (Most Common)
Chrome Trailer Wheel Lug Nut 1/2"-20 Closed Long part # 12CLN-L (Most Common)
Chrome Trailer Wheel Lug Nut 9/16"-18 Open part # 6-53
Chrome Trailer Wheel Lug Nut 5/8"-18 Open part # X1148

We also have the Wheel Lock Set part # RG01-150 for 1/2"-20 lug studs. I have attached a full list of our wheel nut selection for you as well.

@RockyL There's no specific sized lug nut based on trailer size/type. You'll want to measure the diameter of the wheel studs as well as how many threads it has per inch in order to find the correct sized lug nuts.

Answer 1

Trailer wheel lug nuts that are 1/2-inch inside diameter typically have a 20-TPI thread pitch (20 threads per inch). Most lug nuts also use a 60-degree-coned profile like #CE11051, but a 90-degree like #STN569 is also available for 9/16-inch studs.…

For you I highly recommend the DeeMaxx Trailer Wheel Lug Nut #DE93GR. These use the same 1/2" - 20 with a 60 degree cone. They are solid one-piece design, which will more durable and rust resistant than the two-piece options.
