High quality U bolts, and exactly what I needed to repair a broken U bolt on my Sunstream boat lift bunk bracket. Finding 5" square U bolts that are not too long is not easy. These were a little thicker than the original ones I had, but I was able to just drill the holes on my brackets slightly larger (from 3/8" to 1/2"). Shipping was quick.
