The Amazon photo is misleading, it shows the socket has at least an inch or more shank to fit the table but the sockets have I only use 5 /8" so the ugly cutout is visible on the table and this causes the hub to pop out too easily. Also the caps look different from the photo too; they cover the entire rim of the hub unlike the picture See photo Amazon Also I had to file the edges of the bushing as it had sharp burrs.I was expecting a better quality and stronger bushing than the short flimsy flimsy bushings I got.The $14 I paid for paid for a pair, definitely not worth the jacks, they are pretty poor quality despite the packaging saying they are made in the USA my biggest complaint is that the photo is misleading t I would have given more stars d if the photo was of the actual product. I photographed what I received.
