10 Pcs Square U-Bolts 2-3/8 inch Inner Width, Galvanized Steel Square Trailer U-Bolts, Square Bend U-Bolts, U Clamps, Adjustable Length: 40mm-90mm (1-1/2-3-1/2 inches)

Decent quality

I use this to install a toolbox onto my 6x12 dual axle trailer and these fit perfectly.

Would have been nice if they said someplace that these are 8 mm threads and 13 mm nuts. Shame on me, I assumed because it said 5/16", it was SAE bolt and hardware. Wasted 1/2 hour trying to make it work with the other 5/16" hardware I had, surprise 🫤

The plate is thick and less prone to bending when tightened. Threads are clean and give a readonable range of adjustment

Sturdy item. Don’t recall reading how thin the bolt were going to be. Would not recommend these if your installing a fence. More of a hobby Installation bolt.

I used this to attach to a mobile shelter for my farm animals. It’s working well, very strong

They aren't SAE. If you need them for something that requires a 5/16 SAE, these won't work.The bolts are M7 or 7mm. That's about 9/32". The nuts require a 13mm wrench.The description says they're 1/4 and also says they're 5/16. They're neither.

Description says 1/4” but is actually 5/16”. Won’t work for my project.
