They worked perfectly, the old shock absorber bolts were cut off immediately when trying to remove them. The factory design does not allow you to just put regular nuts and thread the bolt. Flag nuts allow for this exchange. The steel seems a little soft, I don't know how long they will last, the screws appear to be from a hardware store and not grade 8 steel. The price is cheap enough, if they break I'll buy another pair and start from the beginning. Better than what I had before.
