TMW (4) Hot Dipped Galv Square 1/2" Dia. U-Bolts x 3-1/16" Inside Width x 4-5/16" Inside Height & HD Washers, Lock Washers & Nuts for Boat & Utility Trailers Fits Down Over 3" Wide Metal

These are really strong. You can tell they will last

Everything is good Price and quality I used it for a boat trailer

These were exactly what I was looking for.

As described and well packaged.

I used the bolts to attach wooden sides to trailer. They were perfect for my needs. They are heavy duty and should endure for many years to come

The first one of these I installed broke immediately, I didn’t even get to tighten it all the way!I did put the others on without issue, but it’s concerning when the first one breaks, gives a low confidence level.I’m hoping the seller will send a replacement piece. I put 3 stars because of the breakage, other than that should be 5. They fit well.

These U-bolts for my 30 yo EZ Loader boat trailer were unavailable locally, was glad to find these whichare USA made, priced fairly, and come with the flat and lock washers. The HDG coating appears robust and should stand up well in our coastal salt water environment. A-1.

Got only five stars because expected to be shouted when tightening . Broke one😠

Quality workmanship and quality material! Item fit exactly to my specs! Measurements were dead on! Was thoroughly impressed. Would def order from this company again.
