Shorter than part obtained locally
3/8” x 3” x 7” Square U-Bolts purchased via Amazon were about ¼” shorter than one I bought at a local hardware store. Either part might be correct depending on how the measurement is made. PLEASE ADD A DIMENSION DRAWING FOR THIS PART. Additionally, the bends were made over a corner instead of a radius. I expect the notches might lead to failure in applications that flex. On the plus side, the threads were noticeably smoother than those on the longer part.

Used for trailer toolbox
Used to tie down my pickup toolbox to my trailer tongue. Works good so far. We'll see as it goes down the road.

It is what it is
Don’t fit like the others I have that are the same size these are just slightly shorter. Not true to size.
