Abstract:

An improved apparatus for the flush mounting of wood structures such as top plates which does not require counter sinking a hole for a bolt and washer. This fastener device has a larger flange area and made of thicker materials than found in the prior art. This gives the present invention added utility when under severe environmental stresses, found in the construction codes.This invention also has the advantages of installing on a bolt that does not protrude a sufficient distance above the surface of the wood. It is also self centering and can act as a separation between the bolt and the wood.The invention utilizes an inverted nut (female) flanged anchor fastening device in combination with a faceted (male) driver with a hollowed annular region for driving for driving the anchor fastening device into place.In certain embodiments, the present design can be inverted and mounted to the bottom side of the top plate between the foundation and the top plate. This gives the added advantage of setting the depth and angle at which the anchor bolt protrudes from the foundation. This eliminates the extra labor to cut the anchor bolt flush with the flat top fastener.
