DEFINITION

Classification: 24/711.4

Having distinct head structure:

(under subclass 706) Pin* having its nonpenetrating portion constructed from material or structure other than that forming the penetrating portion.

(1) Note. If the nonpenetrating portion of the pin either supports or forms guiding, holding, or protecting means for the penetrating portion (e.g., contacts or covers the point of the pin), then it is not proper for this and the indented subclass and is found in subclasses 706.2+.
