A method and apparatus for attaching two members together which includes forming an opening through a first member. A second member has a first portion thereof which is larger than the opening in the first member and a second portion disposed about a longitudinal axis. The second portion is smaller than the opening in the first member and the second portion is divided along the longitudinal axis into at least two sections. A hole is formed through the second member along the longitudinal axis. An elongated member having an enlarged head thereon is placed through a washer, the enlarged portion of the elongated member being larger than the opening in the washer, but smaller than the hole through the second member. The elongated member is placed first through the opening in the washer, then through the hole in the second member from the second portion side to the first portion side of the second member whereby the enlarged portion of the elongated member engages the washer and the washer engages the second portion of the second member. Then the second member is placed in a position wherein the first portion thereof is disposed on one side of the first member and the second portion of the second member extends through the opening unit disposed on the other side of the first member. The elongated member is then pulled from the first portion side of the second member until the washer bends the sections of the second portion apart to the point that the second portion cannot be withdrawn from the opening in the first member, and further pulling the elongated member until the enlarged portion thereof is forced through the opening in the washer whereupon further pulling of the elongated member is accomplished until it has pulled completely through the hole in the second member whereby the second member will be secured through the first member and the elongated member will be discarded.
