DEFINITION

Classification: 411/117

Adjunct carried flat or formation:

(under subclass 116) Device provided with a second, other (i.e., an additional) element, which has the one or more sidewardly facing surfaces or formations and is located on the axis of, and turns with, the bolt head or nut, and wherein those surfaces or formations, rather than the sidewardly facing surfaces or formations of the bolt head or nut, are engaged by the member.

(1) Note. If the flats or formations are located on an extension of the member, rather than on a separate element

which is coaxial with the member, classification is not here in subclass (117) but is elsewhere in this area (116+).

(2) Note. Frequently, the sidewardly facing formations of the additional element comprise a plurality of teeth in the nature of a ratchet.
