Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at the four inch long by 7/16 inch diameter square U-bolts for square frame trailers. This is for a quantity of two bolts. Now, these trailer U-bolts are ideal for boat, snowmobile, and standard utility trailers. The square bend design of the U-bolt simplifies attachment of hardware to your square trailer frame. The parts are zinc plated to resist corrosion, and it does include the two U-bolts, the four flat washers, and the four nyloc nuts.
A few dimensions on this: we mentioned the four inches. The four inches will be measured on the inside to the end of the U-bolt. There's your four inch measurement. The inside dimension is three and 1/8 inches, and the diameter of the U-bolt, again, is 7/16 of an inch. But that should do it for the review on the four inch long by 7/16 of an inch diameter square U-bolts for square frame trailers..

Good service. The right product
I have an older EZ loader boat trailer and these worked perfect with the rest of the items available. Very happy with the products and service.
Everything came in as advertised. Purchased CE Smith bolsters, u-brackets, lag screws and carpet. Added two bunk boards to my Lowe trailer (Karavan). Only had two boards and I wanted extra to support the weight of the boat. Everything assembled easily. My boat loads easier and trailers better. Plus I have the piece of mind of having 4 boards vs 2.
After several attempts at finding the right clamps for my Surco cargo basket, we have a winner! The ones that Surco recommended for my Explorer did not work and they did not have alternatives. Amy was a tremendous help and even had the U bolts sent to her to verify the size before I ordered it. She also found the right size of shackle strap I needed to make this work for me! Thanks Amy and etrailer!!
new hardware and fresh rubber for a boat trailer holding a very old boat. parts arrived early and fit like OEM. If I need trailer parts ever again I will purchase them here.
Wish these were stainless however they are tge correct part to hold down a section of trailer. Being a bit thicker would be longer lasting. Now to receive the correct shackle.
Parts were as advertised and were a perfect replacement for the parts on my trailer. I was pleased to find the parts came with washers and nylon insert lock nuts.
I received my order promptly and all the nuts and washers were packaged with each item. Customer service was excellent and I will tell all my friends. I haven't installed the items purchased but don't expect any problems due to their excellent quality. I highly recommend etrailer.com.
The product I needed was not a common part. But Etrailer had it in stock, at a reasonable price. Product was shipped immediately with the standard shipping selected. Great vendor... would do business with them again, without hesitation!
I found what I needed on this site. Definitely will be returning for any other trailer parts.
Sturdy, and the right fit for my trailers configuration.
The items ordered were just as described and arrived in a very timely manner. Very pleased to order from eTrailer and will do so again as needed.
Parts fit well, I have use ETrailer in the past, they always deliver.
Fit perfect and was good replacement for a rotted bolt.
perfect fit ,only probably was package open and parts spilled out but all there
Parts were exactly what I needed, time will tell how they hold up with corrosion. I probably should of used 2x6 instead of the 2x4 bunks, but there was nothing wrong with these bunks. Time will tell how they hold up.
The U bolts shackle straps I ordered worked great and were high quality parts. I received my order faster than was promised. I will defiantly use these guys again.
Excellently constructed pieces. Service was excellent.
They should work when I get the chance to install them. The weather needs to get better so I can install them outside.
Not much to say - great quality parts at a good price. Ordered this with other items for a nice one stop shopping experience.
Received what I ordered in a timely manner, product is as advertised and exactly what I needed.
Exactly as described. Thanks
Worked well
