1. A method of securing two or more wythes in a building structure utilizing a helical tie member having longitudinal helical flutes terminating at a cutting end at one end and terminating at a remote end opposite the cutting end comprising the steps of:

  • drilling a first wythe pilot hole to a diameter less than a diameter of the flutes on the tie to be inserted;

    drilling a pilot hole in a second wythe to a predetermined depth;

    inserting the remote end of the tie into a reciprocating power driven tool which has a rod which engages and impactingly drives the tie with a hammer like impact in the absence of any driven torque and permits the tie to rotate while confined around its longitudinal axis as a helical bed is developed in the first wythe due to the torque free impact penetration by the tie;

    passing the flutes into the second wythe and continuing to impactingly drive the tie to a base of the pilot hole;

    removing the driving tool from the remote end of the tie; and

    thereafter finishing the remote end of the tie in accordance with mandates of the site.
