Claim 15:
16. 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; and
advancing a fastener through the grip element and through the spacer block within a bore defined by the spacer block, the bore extending under a lower surface of the grip element and bounded by a bore sidewall extending under the lower surface of the grip element,
wherein the spacer block is in the form of a monolithic plastic block that extends directly downward under the grip element and includes a lower portion that extends to a lower surface of the spacer block,
wherein the first fastener hole is defined through the lower portion of the monolithic plastic block to the lower surface of the spacer block and extends below the grip element.
