Abstract

See full text

A metallic insert to be embedded into an opening of a structural member of a material of relatively low strength. The metallic insert has a main body comprising a plurality of coaxially superimposed truncated cones and a recessed portion adjacent to the truncated cones. The recessed portion is provided with at least two radially extending ribs to increase the insert's resistance to relative rotational movements. As a result thereof the metallic insert which requires only relatively small forces to be embedded into the structural member is of high resistance both to extraction and rotational movements of said metallic insert with respect to the structural member.
