Solid hardware with no rough edges. Heavy and certainly capable of holding some serious weight.

These are really nice and heavy. I need u-bolts to secure the wheels to the gates in my pasture... they take a lot of abuse rolling over grassy ground and I've had to replace several. At the local stores - even farm supply stores, it's impossible to find u-bolts like these at any price.I am so happy to have found these.

The ubolt is well made and appears to be very sturdy. My only con is that they did not include bottom plates, which are needed if you attach to the trailers tongue.

These Stainless Steel Square U-Bolts are very good quality. We replaced the U-Bolts on our boat trailer with these and had no problems. The threads are deep and nuts fit and screw down tightly as they should. There isn't much to say about U-bolts! Great Product! 10 Stars!!

I have been using these on a boat trailer to hold on accessories, like ladder mounts. So far so good, appears to be real stainless steel, with no rust spots yet. Not sure if I'd trust them with mission critical and safety components but fantastic for general purpose use. Grreat price!
