walrus,
Note that the wording saying "identified for the purpose" is in a panel members negative comment on the panel action. The official panel statement is "Section 110-14(a) does not permit the connection of a solid conductor with an ordinary machine screw." It appears that the panel is only taking issue with the termination of a conductor directly with a screw and that there is no objection to the use of screws and bolts to terminate lugs and similar devices.
