Confirmat / Firmit Connecting Screws

Confirmat screws have about twice the shank diameter of woodscrews. They have deep threads, and a clearance-hole-diameter shoulder beneath the head, and a head that is slightly larger than the shoulder. Installation requires a special three-step drill bit, resulting in a tight, strong joint.
