Abstract
An assembly for connecting a wooden sill plate to a concrete foundation slab. The assembly comprises a tapping drill bit and an anchor device. The tapping drill bit comprises a flute having a first flute section and a second flute section, the first flute section being longer and having a smaller diameter than the corresponding dimensions of the second flute section. The anchor device comprises a first anchor section and a second anchor section. The anchor device is structured such that the first anchor section is configured for embedment into the concrete foundation slab, and the second anchor section is configured for embedment in the wooden sill plate. The anchor device thereby delivers an advantageous distribution of shear forces that act on the wooden sill plate in relation to the concrete floor slab.
