This subclass includes apparatus for driving one member to pierce and thereby be fastened to another member if the driven member is not an "elongated member" as required for Class 227. Also, this subclass includes structure for fastening by use of an "elongated member" if no driving structure is claimed which would, if claimed, establish classification in Class 227.
