An electrical contact that is particularly suitable for use in high speed, grid array connectors is disclosed. The contact includes a retention member extending along a length thereof. The retention member is adapted to retain the contact within a connector base and to deform upon insertion of the contact into the base to cause a generally straight edge to be formed along a portion of the contact that includes the length along which the retention member extends. Thus, a generally uniform impedance profile may be created between adjacent contacts along the respective portions that are inserted into the connector base.
