Video Transcript for Review of CE Smith Boat Trailer Parts - Stainless Steel U Bolt With Hardware - CE15504A

Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a brief look at the CE Smith stainless steel U-bolt. Now, this heavy-duty, multipurpose U-bolt is intended for use on trailers to help secure brackets, mounts, and cargo to your trailer frame. This is made in the USA of stainless steel construction, making it sturdy and resistant to corrosion. It's gonna be ideal for marine applications.

This includes one U-bolt, two washers, and two nylon lock nuts. And let me go ahead and give you some dimensions of this U-bolt. The inside, we're gonna be measuring the inside dimensions of the U-bolt. Looking at the length first, we are sitting right at three inches long. And looking at that inside width, we are sitting right at four and one, let me line that up a little better.

4 1/8 inches wide on that internal width. And the diameter is 7/16 of an inch. And then looking at how long the threaded section is, we are sitting right at two inches. And that's going to be 14 threads per inch. And it is important to apply grease to the threads before assembling stainless steel hardware to reduce the risk of nut seizure.

Well, that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

The rating is not necessarily for these Ubolts, but the Electric Jack that i previously purchased. It would have been nice to have this size included w/ the jack.



by:

Something is wrong here. Thread pitch is not correct it seems. Nuts would tighten so far and then stop. Would not loosen. Had to cut the nuts off and damaged the u- bolts. Have to order replacements but it won't be from etrailer. 2 weeks I waited for in stocks items to be delivered and then find the product is faulty.

It was all there but when I tightened down the nylon lock nuts on the bracket, the nylon came out on three of the four packs I purchased.

Every part of my trailers suspension fit perfectly and has worked flawlessly. Use my trailer in Salt and freshwater and have had no issues to date. Would buy again

Great, strong Ubolts that look brand new after a year of salt water immersion. These are the only way to go for holding trailer bunks. Do it right, do it once.

  • Stainless Steel or Galvanized U-Bolts For Boat Trailer in Saltwater
    Thanks for the question Clayton, and definitely go with stainless steel U-bolts over galvanized for saltwater.

  • 4 Inch U-Bolt Option For An Older Thule Mountaineer Cargo Carrier
    We do not have an option that is rubber dipped, however I did find a couple options that may suit your needs. The first one is the: -Replacement U-Bolt for Thule Sidekick Cargo Box # TH02943 which measures 4" wide, and is 2" deep. This is a 6mm U-bolt that would not require you to drill new holes, but rather maybe bore out the existing holes if they're smaller than 6mm. The other option I found is the: -CE Smith U-Bolt # CE15504A. This bolt measures 4-1/2" from center to center, or...
