Square U bolts

I purchased two 8mm galvanised square U bolts. They arrived promptly. However, one of the bolts was fitted with four nuts but the other with only two. I had to purchase two more nuts locally.

Reply from U-Bolts-R-Us:
Very sorry for our error. if you had let us know we could have corrected the problem. I have checked all other stock and they all have the two nuts on each leg. So just a manual construction error
