Abstract

See full text

A metal insert, in particular a threaded metal insert, adapted to be embedded in a receiving bore of a plastic part. The insert has a sleeve-like body member. At least one row of teeth projects from the peripheral surface of the body member, which teeth are circumferentially spaced with respect to each other. Each tooth is of a shape such that it diverges from a tooth front end in an axial direction and terminates in an end face extending transverse to said axial direction at a tooth terminal end. Between the teeth are gaps which taper in said axial direction while they remain open between said end faces of adjacent teeth. The teeth ensure that insertion forces for urging the insert into the plastic part are minimal, while resistance to withdrawal of the insert is maximal.
