I was watching a woodworking YouTube video which showed a metal insert being permanently hammered into a pre-drilled hole at the bottom of a table leg. A large machine screw with a padded head was then threaded through an opening in the insert and into the pre-drilled hole. The result provided an adjustable foot for the leg which could extend the length of the total leg by up to about an inch. Here is a bad drawing of what the insert looked like in the video... My question is what are these inserts called? I want to order some but don't know what to look for.
