What are the Right Lug Nuts for an 8-Lug Aluminum Trailer Wheel

Question:

I have a 2005 Montana 3670 fifth wheel trailer - 1/2 inch closed end chrome nuts on it now - aluminum wheels 8 hole however one wheel cam off and I need to replace the lug nuts. Someone said that the 3inch 7/8 that are on the other three wheels have a poor seat - whereas the one you advertise seems to have the proper seat for the wheel. Will the 12CLN-L 1 and 15/16 inch x 3/4 x 1/2 inch20 thread fit for me?

It looks like you have a split spoke aluminum wheel that is not unlike the wheels we carry. For the 8-lug wheels that are similar to yours we recommend trailer wheel lug nut # AM26NR which does have the proper 1/2 inch -20 size and the standard 60-degree cone. If you were using flat lug nuts then those are not going to work as well.

You could also use the longer lug nut # 12CLN-L if you want because it does have the correct threads and 60 degree cone.
