A method of preventing a portion of composite wood from being displaced above a surface and radially outwardly of a fastener upon insertion of a fastener along a longitudinal axis of the fastener into the composite wood, comprising the steps of:
- (a) forcing a first amount of the portion of composite wood beneath the surface by contacting the first amount of the portion of composite wood with a first shoulder of the fastener, the first shoulder of the fastener disposed generally perpendicular to the longitudinal axis of the fastener;
- and
- (b) forcing a second amount of the portion of composite wood beneath the surface by contacting the second amount of the portion of composite wood with a second shoulder of the fastener, the second shoulder of the fastener disposed generally perpendicular to the longitudinal axis of the fastener.
A method of preventing a portion of composite wood from being displaced above a surface and radially outwardly of a fastener upon insertion of a fastener along a longitudinal axis of the fastener into the composite wood, comprising the steps of:
- (a) forcing a first amount of the portion of composite wood beneath the surface by contacting the first amount of the portion of composite wood with a first shoulder of the fastener, the first shoulder of the fastener forming an angle of less than ninety degrees with the longitudinal axis of the fastener;
- and
- (b) forcing a second amount of the portion of composite wood beneath the surface by contacting the second amount of the portion of composite wood with a second shoulder of the fastener.
