A system and a method are provided for installing fasteners. The method includes inserting a fastener (250) into a hole (230), and gripping ends of the fastener via dies (510, 520). At least one of the dies (520) includes a permanent coating having a static friction coefficient of less than 0.2 at a surface (530) contacting the fastener. The method further includes plastically deforming the fastener (250) via force from the dies (510, 520), thereby expanding the fastener into interference with the hole (230) along a length (330) of the fastener such that an amount of interference between the fastener (250) and the hole (230) along the length (330) of the fastener is greater than 38 micrometers and less than 510 micrometers.
