Hi, everybody. Andy here with etrailer.com. And today, we're gonna take a quick look at these trailer square U-bolts. Now, these multipurpose U-bolts are intended for use on trailers to help secure brackets, mounts, and cargo to your trailer's frame. These are zinc plated to resist corrosion. And you're gonna get everything that you see here before me.
You're gonna get two U-bolts, four washers, and four nylon lock nuts. And let me go ahead and just give you some overall measurements here. We're gonna be measuring the inside of this U-bolt. So, the inside length, we're sitting right at four inches long. And the inside width, we're sitting right at 2 1/8 inches.
And then this is gonna be 7/16 of an inch in diameter. And the threaded portion is gonna be measuring right at two inches long. And that's gonna conclude our brief look today. I do hope that it was helpful for you. Again, my name is Andy.
Thank you for joining me..

These U-bolts measure two and one eighths wide. We do not carry a boat trailer U-bolt that measures two and a half inches.
