Just an old tripod and the D-BG5 battery grip. Seems to be relatively soft metal in the socket. Integrity seems okay for the time being, but I'm worried more metal might shred off the socket in and around the worn segment, eventually leading to failure. Do note that the socket is lubricated to reduce wear.

Grip mounts cleanly. Difficulties mounting the camera onto the tripod (it
is 1/4-20, not some non-standard thread) seem to have caused this.
