I bought these U bolts for a project and ended up not using them this time. But I like that they are sturdy and a conventional size and seem to be made of high-grade materials. There were no signs of rust or defects.

We searched high and low for this size U Bolt in several big box stores because we needed one asap. We could not find one, so I went to Amazon!Not only did this fit our needs perfectly, the quality is excellent and much better than what they were offering in the stores for the smaller sizes. It has a heavier weight to it and has held up well since we installed it. Not rust and no slippage. The nuts are still secure, even without using anything to lock them in place.

Works as advertised but should have locking nuts instead of regular nuts.

Perfect! exactly what I needed. The bolts I received are exactly 4" wide. They fit my rear bumper on my RV travel trailer perfectly. Very nice to have them zinc-plated.
