"Needed these to go over some existing bolts on my shed (the ones that hold the concrete panels together) so that I could board out a section.
They looked perfect for the job, but on returning home with my sealed carrier bag I found that they were not fully threaded (they are in the photo). Unfortunately I needed them fully threaded , so a return trip needed.
Can't comment on any other aspect of them as I haven't opened the packet, but they look very strong. Maybe time to update the photo, or at least add a description?"
