As described, seem good quality. The nuts provided are not locknuts, I had to replace them to use on a boat.

Not the correct size, but easy to make fit!
My search for a replacement stainless steel U-bolt for my antenna mast found this one. The existing U-bolt is steel & was rusting after years exposed to the elements.As my review title says, this U-bolt is too narrow at 1-1/8". I needed a 1-1/4" U-bolt, the standard antenna mast size. This is stainless steel, so there's no problems with resizing it on a piece of 1-1/4" pipe. No need to worry about any scrapes or nicks rusting on stainless steel. The resizing was very easy to do on an old piece of pipe. I Hammered the U-bolt onto the pipe, then use a vise to finalize the shape. To my surprise, the plate still fits perfectly! :)The pros:+ $6.46, which included free shipping, or $2.10 + free shipping if you get this when it's an "add-on item"!+ 300 grade Stainless steel, so it will never rust & it will last forever!+ Comes with a stainless steel plate & 2 stainless steel 1/4-20 nuts.The cons:+ Doesn't come in 1-1/4" size.I bought 3 of these & I may up the product rating to 5 stars after I install one of these U-bolts.► Update - August 8, 2013I installed one of these today on a 1-1/4" antenna pole & the resizing made the U-bolt a perfect fit. I've decided to up my product rating to 5 stars.► Update October 21, 2015I have 2 of these installed now. The first one I installed on an antenna pole, 2 years ago, still looks like new! Not wanting to be without a couple on hand, I just added another one of these on my Amazon order. I couldn't pass up the $2.10 + free shipping price!.

Received parts
Received both parts ordered. One part was loose in shipping package and other part was enclosed in a taped shut clear plastic bag. When I opened the clearbag I found that one of the nuts was missing. After checking everything I could not find the missing nut.

Decent quality stainless steel u-bolts.
I used these to bolt in some aluminum tubing for a removable handrail. Since my boat is made out of aluminum, these were a must. The best part for me, thy are threaded for us people in the USA. NOT METRIC. I used the backing plate, but used nyloc nuts instead of the supplied nuts. If you need a solid, non rusting u-bolt, these will do the job.
