Claim 18:
19. A method of using a fastener unit, the method comprising:
placing a spacer block adjacent a first board so that the spacer block engages a first side surface defining a first groove in the first board so that a thickness of the spacer block is positioned to establish a preselected gap between the first board and a later placed adjacent second board;
inserting a grip element, which extends from the spacer block, into the first groove;
inserting a first resilient compression element, which extends from the spacer block, into the first groove so that the first resilient compression element bends toward a reference plane that is aligned with the grip element, and forcibly engages a first groove surface of the first groove to suspend the spacer block adjacent the first board before the later placed second adjacent board is placed adjacent the first board;
providing a second resilient compression element distal from the first resilient compression element, the second resilient compression element extending from the spacer block, the first resilient compression element including a first wing extending to a first tip, the second resilient compression element including a second wing extending to a second tip distal from the first tip; and
advancing a fastener through a first fastener hole defined by the spacer block and a second fastener hole defined by the grip element to engage a head of the fastener against the grip element disposed around the second fastener hole and pull the grip element downward to thereby move the grip element and the reference plane toward the first tip and the second tip; and
bending the first tip and the second tip toward the reference plane while the grip element remains stationary relative to the reference plane.
