An electrical contact is provided for press-fit insertion into a circuit board, which produces a large retention force (resistance to pullout) with only moderate hole distortion, and which can be reliably produced at low cost. A press-fit section ( 14, FIG. 4) of the contact is of largely I-beam cross-section, with upper and lower flanges (60, 62) that each have outer faces (64, 66) for abutting the walls of the circuit board hole, and with a web (70) connecting the flanges. The entire cross-section of the contact is of rigid construction for minimal deformation when inserted into the hole, so most of the deformation is of the hole. Each flange face has about the same radius of curvature (C) as that of the hole, and the web is narrower than the flanges, but thick enough to avoid substantial bending.
