A socket apparatus comprises a base portion defining an array of contact cavities. A plurality of contacts are inserted into the array of contact cavities defined in the base portion. The base portion includes a top side and a bottom side and a plurality of ribs extending from the bottom side. Each rib defines at least one sidewall that engages with an anchor of a contact to securely mount the contact. Each contact includes a mounting portion having a first anchor and a second anchor extending from the mounting portion and operable to engage a mounting surface of the base portion to securely mount the contact. The first anchor provides a first anchor force for the contact to the base portion that is substantially greater than a second anchor force provided by the second anchor to the base portion.
