A center longitudinal hole is arranged in that footing stud rear end that receives and locks to a pointed cone base end edge of a tack that is fitted therein. The tack includes a tack shaft whereto is axially attached, on one end, the pointed cone base with a broad head secured to the other shaft end. The tack broad head is disk shaped and includes spikes that project at spaced radial intervals from the undersurface thereof, parallel to the shaft, and includes a center axial threaded post that extends outwardly from a top surface thereof. Which threaded post is for turning into a threaded end of a tack driver.
