Galvanized Steel
Galvanized steel parts are hot-dipped in zinc after being stamped. This creates a coating that is typically 3 mil to 5 mil thick. This thick, all-around coating allows galvanized steel products to provide years of use without rusting or corroding.

These sturdy square U-bolts let you secure 2 double U-bolt bolster brackets or 4 standard bolster or bunk board brackets to your boat trailer's frame. Galvanized steel is durable and corrosion resistant. Hardware included.Shipping box half open. More tape?? bolt package open not all lock washers included. Nothing major. I’ll get another one at Lowes
The U-bolts need to be threaded further up the bolt. It may work ok for larger sized boat trailers that have thicker rails. I have a 16 foot jon boat that has a trailer with rails that are thinner in depth. So matter which way I placed the bracket, the u-bolt would not tighten all the way down. I had to create a spacer to be able to tighten the bracket with the u-bolt. Threading the bolt further would solve the problem.
Used these as part of a full boat trailer rebuild. They were sized perfectly and of very high quality. After a year of use these are performing excellently.
They where easy to install... Heavy duty ... Worth every penny big to Etrailer...
My jetski trailer needed new bunks and hardware, I called these guys to verify what I needed. They hooked my up with good quality parts. I do wish however they would have included the lag screws needed for the bunks.
Bought several parts from eTrailer to complete this restoration and transformation of a 1958 trailer to suit my needs today. Couldn't have done it in only 4 days without the help from this great company with quality products!
Great quality1 fast shipping
Ordering was smooth and shipped out from ETRAILER was lightning fast.
U Bolt and Bolster bracket are heavy duty enough. They should screw down the swivel on bolster bracket a lot more because it was pretty annoying moving around while mounting it.
The guide rail bracket holes were a bit too close to the frame, making it difficult to use a ratchet
end wrench placement and removal difficult. Without using ratchet, it will take you several minutes to put a nut on just one.
Quality is good!
Great products just wish the shipping end would of kept the box in better condition. Appreciate all the customer service I’ve received and will be using the company soon for another trailer!
GREAT Customer Service!! Seth worked with me to get the exact size and type of bolts needed for the job. Prompt delivery and up to date tracking. This is how a business should handle their customers. Bolts are heady duty galvanized. Will easily replace the rusted bolts that hold the bunk board brackets.
Completely updated the axle, suspension, and added roller bunks to my waverunner trailer. Have taken the waverunner in for the winter and back out for the summer one time. All components were great and the trailer rides really well!
Very impressed with e trailer everything I ordered was received the way I wanted it everything works great rebuilt a boat trailer From the ground up very happy still tows down the highway no problems
All the parts came as ordered,very pleased with everything. Got the bunk boards mounted and my boat seems to sit on them as i expected. I purchased stainless steel lag bolts to attach the bunks to the brackets. Parts arrived UPS all packaged in a large box with lots of packing paper,loose items all wrapped nice so nothing got lost.
etrailer has always delivered for me. I’ve ordered a wide range of items which get here on time and good quality. These 1/2” galvanized U bolts were perfect for my boat trailer rebuild!
all expected parts arrived in excellent condition and as promised.
dimensional diagrams for the CE Smith Bolster & Swivel bracket would be helpful for choosing an accurate size.
Otherwise, I'm very satisfied with my order.
Good quality U-bolts and swivel bracket assemblies. They are not a direct fit for my Caulkins trailer. I will have to devise a tapered shim for the bolsters so that they will run parallel to the outside rails. I had not counted on a custom installation.
Good quality product. Seems to be well constructed. All parts were included. The best part was not having to hunt down individual components when you can buy a complete set. Packaging was good. This will make installation of bolster brackets for my boat trailer a breeze. I would definitely buy from etrailer in the future.
The products purchased were solid and of good quality. I'm impressed.
We purchased a used Jon boat and are upgrading the trailer and boat to for our satisfaction. We would not hesitate to purchase other products for etrailer. The videos were very helpful and informative. If I can I will add photos of before and after, soon.
Excellent quality and great price. Was thinking the U-bolts were a little high and I could save at walmart but I bought the recommended one from etrailer and I'm glade I did. Much higher quality and did not realize how heavy duty they needed to be. Great job etrailer!
The parts came quickly, all well packed. The coating on them seems very good. Love the way the nuts and washers are packaged and ty wrapped to the u bolts. They should work out well.
Excellent product, exactly what I was looking for. Thank you for sending it so quickly. Will definitely do more business with etrailer.com
the products are of good quality, however the wait time was long. I was put back twice because they said the supplier of the parts had not shipped them in a timely fashion so I waited for 2 weeks extra for parts to arrive
Great quality trailer hardware
delivered before due date
all good
