A jack stand apparatus enables operators to screw adjust a load support column relative to a column support base for fully completing load-bearing distances between loads and opposed support surfacing, and thus improving safety of jack stand applications. The various embodiments of the jack stand apparatus according to the present invention may all be said to comprise a shaft support structure, a shaft construction, a pawl assembly, and a screw mechanism. In the preferred embodiment, the shaft construction is a screw type element and includes external threads. A pawl element is cooperable with the external threads, and the screw shaft construction is telescopically positionable relative to the shaft support structure for engaging an overlying load. The pawl element is engagable with the helical threads for preventing downward movement of the screw shaft construction relative to the shaft support structure for supporting loads thereupon.
