DEFINITION

Classification: 411/305

Externally threaded element adapted to be compressed radially inwardly:

(under subclass 259) Device wherein the externally threaded element is so formed (e.g., with a threaded portion which has a hollow core, with a threaded portion which is slotted longitudinally, etc.) that its engagement with a mating internally threaded element results in at least some displacement of its threaded surface in a direction toward its longitudinal axis.
