Sounds like you have the wide sockets. The ones that bind up are the 3/4"
pins. Especially the screw in ones. The pin is stainless and the bushing in
the socket is delrin. Most any penetrating lube does penetrate the delrin
to a certain extent, and swell it, which ends up locking it to the pin even
harder.
