Video Transcript for Let’s Check Out the CE Smith U-Bolt

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's frame. And this is made in the USA of a stainless steel construction, making it sturdy and resistant to corrosion, making it ideal for marine applications. So, with this U-bolt, you are gonna get two washers and two nylon lock nuts.

And again, just one U-bolt. And let me give you some dimensions here. I'm gonna be measuring the inside dimensions. So, beginning with the length, we are sitting at four inches long. And looking at that inside width, we're sitting right at 2 1/8 inches wide.

And the diameter is going to be 7/16 of an inch. And measuring the threaded section, the threaded section is right at two inches long. And there are 14 threads per inch. And it is important to note that you should apply grease to the threads before assembling the stainless steel hardware to reduce the risk of nut seizure. Well, that's going to conclude our brief look today.

I do hope that it was helpful for you. Again, my name is Andy. Thank you for joining me..

Exceeded my already high expectations. I live in rural Hawaii and my complete boat trailer axle down to tires was delivered within a week of order with reasonable shipping charges.. Local place gave me runaround 3x already. This saved me. Now I can go fishing again!

Dimensions and sizing can be difficult, even if you are used to these things but trailer makes it super ez.. With videos and detailed things. Thank you, I will definitely do business again!!!



by:

Etrailer is one of the few places to buy ss bolts. Thank you.



by:

Didn't realize that I had ordered stainless u bolts. The nuts and bolts must be different grades of stainless. One of the nuts galled.



by:

I couldn't believe how quick the order came. Excellent condition and great quality parts. Thanks you etrailer.

Perfect size and quality was excellent

I needed that exact size U-bolt in stainless steel to keep me from making modifications.



by:

Major issue with the lock nut, once fastened onto the u-bolt up to hand tight, whether using hand tools or drill, several nuts seized and could not be loosened rendering the u-bolt useless as it could not be properly tightened. Eventually the bolt gave way and snapped off. Quality control missed big time on these!



by:

Something is wrong with this item. Maybe and issue with the nylock nuts Not really sure. They will tighten partway, and then go no further....and you can't get them unthreaded. Had to cut off the U-bolt. I'd think that somehow we messed up and cross threaded them or something, but that was not the case. Definitely a product defect.



by:

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.



by:

It was hard to find the size U-Bolt, but it came exactly what I needed and on time. Thanks, trailer, and I will use it again.



by:

I never write reviews, but I want to warn other buyers. Use different nuts than what comes with these bolts. I saw the reviews that said they cease to the bolts & won’t move, but thought it was operator error & I wouldn’t have any problem. I bought 4 bolts & 2 of them had the nuts stick before they were even tight. They wouldn’t move either way, resulting in the bolts having to be cut off & one being too short to use. Do what you want, but I wouldn’t risk it again. I’d use different nuts.



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.



by:

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:

The bolts were exactly what I needed. Shipping was very quick. I found them to be a great price for stainless.



by:

These u boats are a quality product. I am replacing the u bolts on my boat trailer with these to hetbridnofnrusted parts. The pricing was very competitive and actually better than I could get locally. Service was prompt and accurate.

  • Are There Galvanized and Stainless Steel U-Bolt Options Available
    Yes, we do have stainless steel and galvanized square u-bolts available. The CE Smith U-Bolt - Stainless Steel # CE15501A has the same 4" Long x 2-1/8" Wide x 7/16" Diameter measurements as the Trailer Square U-Bolts # 7162184UB you were looking at. I have also listed all of our galvanized and stainless u-bolts below for you. Galvanized: - CE Smith U-Bolt - Galvanized - 4-1/16" Long x 1-9/16" Wide x 1/2" Diameter # CE15282GA - CE Smith U-Bolt - Galvanized - 3-9/16" Long x 1-9/16" Wide...

  • Should Stainless Steel Or Galvanized Bolt Be Used To Mount Trailer Tongue Tool Box In Coastal Area?
    Stainless steel fasteners are going to be a much better option for securing a Trailer Tongue Toolbox # 350970 to the front of your trailer. Galvanized are going to be able to wear through the coating and begin to corrode while stainless is throughout the bolt and will not corrode and rust away. We do have a Polyethylene Box # 3371701680 if you are wanting something lighter and not aluminum. This box only weighs 21lbs versus 37lbs for the aluminum above. We do have the U-Bolt # CE15501A...

  • Recommendation For Attaching CE Smith Bolster Bracket # CE10100A40 Onto Angle Iron Crossmember
    With mounting the CE Smith Bolster Bracket # CE10100A40 on an angle crossmember rather than a square you will want to use some square tubing to act as a gusset so a U-Bolt # CE15501A will hold the bracket tight against the crossmember. This will ensure it does not slide on the crossmember. I would not recommend drilling into the crossmember as it most likely is not large enough for multiple holes to secure the bracket properly.

  • Needing U-Bolts to Fit Around 2x3 Trailer Frame Member
    Given the dimensions you provided, I believe that a u-bolt kit such as # CE23103 that's typically used to mount a 2 inch square trailer axle to the leaf spring pack would be your best bet. The kit includes two assemblies, each of which includes two 4-1/2 inch long 1/2 inch U-bolts with a 2-1/8 inch inside span, two bolt plates and the necessary nuts and lock washers. I've linked to a product description video for the U-bolt kit I recommended.

  • U-Bolt For A 2-1/8 Inch Trailer Frame
    The U-bolts we offer with designed to fit a 2-1/8 inch frame are part # CE15501A. We do not offer any other U-bolts designed to fit a frame that size. I pulled one of the part # CE15501A U-bolts from our warehouse and took some measurements for you. I have enclosed a photo with the dimensions noted you can check out. The length of the threads you asked about is 2 inches.

  • Recommended U-Bolt to Mount Toolbox to Aluminum Trailer Frame
    I recommend using the CE Smith U-Bolt # CE15501A because it is stainless steel, measures 2-1/8" wide x 4" long, and it includes the washers and nuts you need for the installation. Ultimately you will still get galvanic corrosion over time but stainless steel will react much slower than the zinc-plated options will which is why this is your best option for mounting your toolbox. If you need to make the U-Bolt shorter you can definitely do that as well.

  • 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. Stainless steel is going to last longer than galvanized in that environment so it's the better option. Here are the options for stainless steel U-bolts depending on the size you need: - 3" Long x 3-1/8" Wide: CE Smith U-Bolt - Stainless Steel # CE15502A - 3" Long x 4-1/8" Wide: CE Smith U-Bolt - Stainless Steel # CE15504A - 4" Long x 3-1/8" Wide: CE Smith U-Bolt - Stainless...
