Insert of metallic material to be installed in thermoplastic and thermosetting materials

摘要

An insert (10; 10') adapted to be inserted into a plastic material consists of a body (12) of a metallic material having a side prismatic surface (14). A respective longitudinal spline (16) is formed on at least one of the faces of the prismatic side surface of the insert, which extends along its directrix. Moreover, at least a circumferential groove (18) is formed in the prismatic side surface of the insert, which intersects the longitudinal spline. The circumferential groove has conical sidewalls (18a, 18b).
