I received the 4 pack of U-bolts on time and sufficiently well packaged however they are NOT M8 U-bolts. The U-bolts I received were definitely M6. They seem like decent quality, and I can probably use them somewhere, but not for the intended purpose. If M6 is what you are looking for, these should work for you. If you need M8, as in the product description, you will need to look elsewhere.

Not sure what happened to the buyers before me, but the 12 I purchased came with all hardware, including the washers.Also, the description is misleading since it says M8 thread in the title but M6 in the specification. I took one of the nuts to the hardware store and it's M8x1.25.

The square u-bolts were exactly as specified and appear to be of excellent quality. I used these for an archery draw board and they worked perfect.

Inconsistency of material.I ordered the exact items two different times (repeat order) and they came in with different size bolts. The U shape was the same size but the material was smaller on the second order with smaller nuts.
