Today we're going to take a look at the replacement 3/8" diameter nut for the trailer suspension u-bolts or 12" brake assemblies. Now this 3/8" diameter nut is designed for use with u-bolts, it'll help secure your trailer's axle to it's leaf springs. Or also to fit 3/8" mounting bolts on your 12" brake assemblies. Now when you do use this on a brake assembly, it will also require a lock washer, which we do sell separately on our website. It's part number 38LW, it's also listed on this product page as a related product. Again the size on this nut is 3/8" by 24 threads per inch.
The overall diameter, or the wrench socket size, is 9/16 diameter. Happen to pull a 9/16 socket, and you can see it's made exactly for that. Now this part is for a quantity of one replacement nut. This nut is also available in a zinc finish if you need, it's part number 38NZ, and again it's sold separately on our website. But that should do it for the review on the replacement 3/8" nut for trailer suspension u-bolts, or 12" brake assemblies..

3/8" Diameter replacement nut is designed for use with the U-bolts that help secure your trailer's axle to its leaf springs.

I am on Evacuation Advisory for the huge Rim fire that is currently happening in California. I live just a few mile from the perimeter of the blaze. The fifth wheel is all loaded up and ready to go but I was having troubles with the electronic brakes. Now I should have tome to get these new ones in place if and before the word to evacuate comes through! Thanks again!
Replacing the brakes on a 50 year old FAN camper. After being assured that it had 10 inch brakes by another company"s "expert" because it has a 3500# axle, I finally received the correct 12 inch brakes from eTrailer. They arrived very quickly, and packaged well. The installation went almost as easy as the very helpful online video showed. Only difference was I had to slightly tighten the brakes to slide the hub over them, even though they are self-adjusting once in service. I have never owned or worked on a trailer before, and the installation was relatively easy. Thank you to George J for the followup email within 24 hours of delivery.
Nuts and bolts are nuts and bolts but I can report that the self-adjusting brakes have worked well on our two-thousand mile trip this summer through the mountains of Utah, Idaho, Nevada, Oregon and Washington. They stop straight and true and don't seem to fade on those long down grades like the infamous "Cabbage Hill" near Pendelton Or.
bought a brake assembly that needed fastening to the axle; these nuts, bolts and washers were just what I needed. Thanks George J.
The whole order was perfect. I'm rebuilding the running gear on a1976 3 horse slant then remodeling the whole trailer by converting the trailer into a communications trailer for HF radio for disaster response. Front area will be living quarters. I am in our State Guard as a radio operator and also in county emergency management. This trailer will be my shelter and operating station when deployed to hurricanes and such. Since I'm spending my own funds on this, the good prices on etrailer are greatly appreciated.
My package arrived on time just as I expected. I was a bit disappointed with the packing. Everything came in one box. The nuts were not in any bag they were just loose in the box. I ordered 10 but I only received 7. I think the other 3 fell out the bottom of the box that was not completely sealed with tape. You might want to put small parts in a zip lock bag. I ended up replacing new bolts one one side instead of both.
US made product, great service from Erika who sorted out my information as to what type of brakes I needed, and fair price. I was very pleased with the follow up emails and the pro service that was provided. Never used Etrailer before, but will be a return customer. Thanks

Thank you so much for all your help Amy J.
Ordered lots of parts on Monday, received most of them by Thursday. The received parts were well packaged and undamaged. A few of the parts they didn't have in stock so they had those drop-shipped to me which should be delivered in the next couple of days.
No supplier I have ordered any parts from has such a great technical reference web site or personal customer support. Yea, Rebecca - Well Done! Yes, I'm very happy with the pricing.
Thanks for your great support and I look forward to doing business with them again. More info to follow as soon as I can get the parts installed on my trailer.
The parts have worked out very well and have not had any problems. Thanks again for the parts and good service.
