DEFINITION

Classification: 24/562

Corrugated or toothed face:

(under subclass 561) Engaging surface having at least two (a) engaging recesses distinct from any initial taper of the engaging surface, or (b) engaging projections or pointed teeth.

(1) Note. The initial taper of the engaging surface is commonly used for smoother, easier, or guiding initial contact with the structure-to-be-secured* as it enters the resilient* gripping member. It is not considered a recess but may form one side of a projection or tooth.
