Poor quality product. Of the 25 in the box, the nut screwed freely on the bolt in only 4 or 5. In most cases it was difficult to start the nut, and in about half, the nut would not run easily up the shaft even with lubricant. Two bolts were unusable because the nut would not turn. Possibly due to the galvanising but low standard machining seems more likely.

The photo on the box is wrong as the thread goes all the way up which is good for me because I need it to

After picking up the bolts I found the nuts were not part of the purchase, this was not indicated when purchasing on line.

I needed these for the main support.
Very low tensile strength, broke 2 of these out of 8 going into a hardwood gate even using a large pilot hole.
Good product to use when you want to prevent rusting on the job at hand, the galvanising is a little coarse, run the nuts down the thred first, they then are easy too use.
