Video Transcript for Americana Tires and Wheels AM90049 Review

Today we're going to review part number AM90049. This is the Americana 1/2 inch by 20 trailer wheel lug nut with the chrome-plated finish. The 1/2 inch by 20 designates the size of bolt that this will fit on; 1/2 inch is the diameter and the thread 20 means 20 threads per inch. Usually on most lug nuts they will be stamped. If you see on this one, it'll say 1/2 inch by 20 to let you know what size this is. This also has the standard 60-degree cone you can see here that will fit the 60-degree taper of the wheel you put it on.

It is a chrome-plated finish for durability and corrosion resistance. To give you a measurement on this; overall length of this lug nut is 1-3/4 inches and the hex head size or socket size you would need to use on this is 3/4 of an inch. I happen to have a deep-well 3/4 inch socket here, you can see it fits perfectly right on there. Just wanted to show you on your trailer wheel, most trailer wheels will just have a standard open-end small lug nut. This longer lug nut with the closed end you could put on there. It gives you a little bit longer reach, also a nicer finish, but the main advantage of using the longer lug nut is lots of times people will change from a steel wheel to an aluminum nice wheel and the aluminum wheels usually will have a deeper middle to where your lug nuts are so instead of having a shorter lug nut like this on it you need a longer lug nut so you can access it with your socket.

These longer lug nuts like this will work a lot better in the aluminum designed wheels. That should do it for the review on part number AM90049. This is the Americana 1/2 inch by 20 trailer wheel lug nut with the chrome-plated finish. .

Americana Trailer Wheel Lug Nut - Chrome Plated - 1/2"-20 - AM90049

Average Customer Rating:  4.8 out of 5 stars   (248 Customer Reviews)

Trailer wheel lug nut fits 1/2" diameter wheel bolts and is chrome plated for durability and corrosion resistance.


I bought these closed end lug nuts to replace the old worn out open end ones on my EZ Loader Boat Trailer. These should protect the studs better and look a lot nicer. The fit was perfect 1/2-20 for my axle. These axle hubs were rebuilt by me and changed from oil hubs to grease hubs with new bearings, seals and Brake Buddies obtained from I also purchased the nice aluminum wheels and upgraded Load Range D Kenda Karrier tires, 175/80R-13 already mounted from etrailer. I thought the price was very fair and I didn't have to mount the new tires on the ugly original galvanized wheels. Great customer service as always and the parts are good quality. Ignore the brown haze on the wheels, it is just a reflection. The wheels are spotless and shiny!

Perfect, no issues at all and they look nice and have protected the studs better than the small open ended lug nuts.

perfect addition to my new tires and ri ms


Work great with my wheel and tire combo


These wheels are beautiful. They totally changed the appearance of my travel trailer. I am 100 percent happy with them. Thanks


These wheels(rims) were exactly what we we were looking for and we think this is a significant upgrade to our 2008 Jayco JayFlight G2 travel trailer over the original, somewhat worn old wagon wheel style rims that came with the trailer. The service from etrailer is just as important to this review as the wheels however.
We had a problem with one of the HiRun tires installed 5 yrs ago while we were on the road from North Carolina to Delaware. Upon closer inspection, and not being able to find DOT Codes, we decided to purchase new american made tires while on the road.
After sourcing the tires here near the beach in Delaware, I called etrailer and wound Talking to Tommy C. On Monday morning I ordered the four rims 4 center caps and 24 Lug nuts, and on WED.(!!!Missouri to Delaware in less than 48hours) they were at the tire dealers and ready to have the tires mounted on them. Friday on our way to the next stop we stop by the tire dealer, get the closest thing to a Pit-stop off with the old - on with the new, and up the road. Excellent Products with Outstanding Service!!!!


I purchased a full set of these lug nuts after a flat and the semi disaster that followed. After having a flat in my T32C Jayco toy hauler, I proceeded to remove the wheel with my cordless impact. The plan was to make fast work of this since I was working along a busy interstate highway. The stainless clad steel nuts that came on the trailer cracked the outer shells off on two of the eight nuts which caused the nuts to now be too small for the socket and not easily removable. After pounding a socket on that was too small, I finally removed the offending lug nuts and got down the road. These chrome plated steel nuts have no outer shell to break off and along with a new tight fitting 3/4 socket should cure this problem.


I just received the product. it looks great. Jesse was very helpful and knowledgeable. This will be my go to place for my trailer needs...


These lug nuts really improved the looks over the smaller acorn type that my trailer came with. I like how the threads are not exposed anymore. I also found that it is very easy to scratch up your rims around the lug nuts with the lug wrench when you have the acorn nuts. These are much longer and the lug wrench does not even come close to rims anymore. They shine up nicely too. Nice way to upgrade the wheel area of your trailer.


Nice looking fits great and improved the trailer’s wheels. The older lugs had rusted really bad. The motorcycle trailer looks great now.


Purchased an extra set of stainless lug nuts and an extra set of chrome plated lug nuts for my AM22319HWT wheels after noticing a couple of the original chrome plated lug nuts were showing signs of corrosion. Shipping was amazingly fast for standard shipping. Communication and customer service ahead of the purchase were also superb. I use my beloved classic Whaler in saltwater, so I can't truly expect trailer components to age as they would in freshwater. Wheels look great and have held up pretty well considering what I subject them to. All in all, very satisfied.


These are very nice looking lug nuts, look great with new wheels I got from e-trailer

Still very happy no issues with 4000 miles on them.
Mike C - 01/20/2019


EZ to order, lightning fast shipping, the chrome center caps and lug nuts look great on my trailer! This trailer is about 25 years old and was just repainted and had all of the wood deck and sides replaced. Of course I had to make the wheels look good too!!


Very satisfied with both of my orders!!
eTrailer for parts for your trailer!!


Arrived on time, packaged well and excellent replacement part!


Chrome lug nuts came well packed and look great. Along with the center caps and trim rings my wheels look alot better than before.


Good compliment for my wheels, fast shipping! Thank you


These lug nuts are excellent quality for the price. With some One Grand polish they shine up nicely. After much research, we couldn't find the right length nuts for our Ford truck wheels. These replace the much uglier ones. They fit the bill. And now our trailer wheels will finally match!


These nuts were purchased to stop the lug studs from rusting.
I have not removed any to see if it was accomplished but the outside of the nuts are already rusting badly.


Everything is excellent! Great product, shipping and service! Thank you so much


This is a great company to to purchase from. I ordered my wheels, tires and the assessories on Thursday night late and by mid day the following Tuesday they were delivered. Great company, great product, quick shipping.


Great lug nut. Looks even better than the picture and fit perfect. Replaced old nuts that have a cover on them which can give problems when taking them off. The new nuts are solid metal and no problem to take off or put on. You can see what happens to the old nuts and then how great the new ones look.


Excellent customer service, fast delivery and a great product. I will recommend to all my friends. Thanks and keep up the good work.


Placed order and received product within 4days on time / bullet lug nuts / thank you rep. Noel, and Etrailer for fast service and keeping the customer informed


As shown, good quality

  • Recommended Lug Nuts for Aluminum Wheels on 2012 Classic Limited Trailer
    The correct size lug nut you need for your 2012 Classic Limited Trailer will depend on what type of wheel bolts you have on the trailer hubs. I recommend taking a few quick measurements on your existing lut nut and wheel bolt to verify the correct replacement. If your wheel bolts have a 1/2 inch diameter with 20 threads per inch, the Americana Wheel Lug Nut # AM90049 should work well. These longer lug nuts are usually needed with aluminum wheels that have a deeper middle section. I have...

  • How to Determine the Correct Lug Nuts for an RV
    The socket and wheel size has no bearing on the correct lug nuts for your RV. In order to determine the correct lug nut for your RV you will need to remove one of them and take it to your local hardware store. At the store they will have a series of different bolts you can thread the nut onto which will then tell you both the diameter and TPI/pitch. For example, the Americana Trailer Wheel Lug Nut part # AM90049 works with 1/2"-20 lug studs. I have attached our selection of lug nuts for...

    When it comes to The Aluminum Bobcat Trailer Wheel - 14 inch x 5-1/2 inch Rim - 5 on 4-1/2 - Gunmetal Gray # LH57FR, the wheel bolt size is 1/2 inch-20.

  • Will Karrier ST175/80R13 Radial Trailer Tire with 13" Aluminum Wheel Fit a Shorelandr Boat Trailer
    Yes, the Karrier ST175/80R13 Radial Trailer Tire with 13" Aluminum Wheel # AM31998 is a great choice for your Shorelandr boat trailer. The wheel in this combo has a 5 on 4-1/2 bolt pattern and will likely require different lug nuts because regular lug nuts are not long enough. For a longer lug nut use # AM90049 sold in quantities of 1. The price listed for the tire and wheel is for one tire and wheel combo.

    The wheel bolt hole diameters of the # AM20758 is just slightly over 1/2 inch which allows only 1/2 inch wheel studs to fit through. You wouldn't be able to fit a 9/16 inch or larger stud through the hole. The lug nuts to be used with this wheel do have the 60 degree cone shape like the part # AM90049.

  • Determining Lug Nut Size for Sendel Trailer Wheel
    It is likely that you will need a lug nut like the Americana # AM90049 that threads onto 1/2"-20 lug bolts. That being said, the wheel itself does not determine the necessary lug nut size. The best way to determine the correct lug nut is to remove one and take it to your local hardware store. They should have a series of bolt that you can test fit the nut on to determine the correct thread pitch and diameter. I have attached a review of the wheel and lug nut for your reference.

  • Recommended Wheel Center Caps And Lug Nuts for Fleetwood Avalon w/ 14 Inch Aluminum Rims
    From the photo I see you have a 5 lug wheel. Typically, a 5 lug wheel would have a 4-1/2 inch bolt circle and a 3.19 inch pilot (center hole) diameter. If this is the case, the # 319EZ center cap you referred to would work just fine for you. Just to be sure, I'd recommend pulling one wheel and using an accurate measuring device like a digital caliper to find the pilot diameter. If your wheel studs are 1/2 inch diameter, 20 threads per inch (very likely), I'd recommend the # AM90049 lug nuts.
