Overall rating: 4.8 / 5 from 146 reviews.
Ordered square 5/8" u-bolts. 8 of them were 13" length, 8 of them were 17" length. I needed strong top quality u-bolts for my overhead crane. These were extremely well made, accurate bends, plenty of thread length. The nuts and washers are legit long nuts, and hard washers for the application. Did not even have to squeeze the ends to make it fit through the u-bolt plates. Great stuff. 100%

I had broke 2 u bolts on my older backhoe needed a special u bolts . You had what I needed and at a decent price
Perfect fit 👍
Did some leaf spring work on my 55 Chevy. Couldn’t seem to find the right U-Bolts at any local parts centers. Found these guys online, figured out what I needed on their website and made an order on a Thursday, they showed up at my place on Tuesday in Northern Wisconsin! The quality and fitment was absolutely perfect. I will definitely recommend The U-Bolt Store to anybody working on a custom project. Thanks, Eric from Superior WI.
I ordered these u bolts for my 1968 f350 dually and they fit just like I specked them.
I used two custom 5/8” u-bolts (one round, one square) to hang an old ski chairlift chair in my yard. Came out great. Makes a fun yard swing. The quality of the custom u-bolts was outstanding.
Perfect fit! We are restoring a 1952 F2. We put axles from a Dodge Dakota under the frame so I can have power brakes and power steering.
Wow, what more could I say, I got exactly what I needed in only 4 business days. Great job!
Well made exact fit and were exactly what I wanted.i do recommend and will buy again
Easy to order, grade 8, quality made, perfect fit, fast shipping. Customer service follow up. Quick email response on a question for a second order. They aren't the cheapest but when you want the best it's ok to spend the extra. Since these are used on out F350 to trailer 5th wheel units we had to have the safest and best u bolts I could find. UBoltstore.com to the rescue. Thank You for a great product and great service
Great service and quick delivery. Thanks
I custom ordered three (3) different sized 5/8" square U-bolts and each was made perfectly. The measurements were spot on, the threads were in perfect shape and the service was very fast. I highly recommend utilizing this company for any U-bolt needs you may have.
Arrived quickly fit perfect
Heavy duty u bolts exactly what I needed to tie my flatbed to my f350 frame.
U-bolt arrived in good condition. One leg was longer than the other, but for my application on a fifth wheel hitch bike rack, it doesn't affect anything. The u-bolt looks to be high quality, threads look good.
Bolts were a perfect fit. My order was easy to make on line and was received very quick.
Just right for the rear end on my 86 gmc c6000
Good job

The custom U-bolts I ordered for my 1972 F-250 fit perfect. If I needed u-bolts for any other vehicle I would order from you again.
You guys rock! Perfect to my specs and quick and fair price for quality and shipping. My prototype not installed yet but gets me a step closer.
The bolts that I needed were not standard sizing so I was very pleased to get them. Ordering was easy and delivery was fast.
