An awl screw is a spike-shaped twisting device, a particularly sharply sharpened awl with a screw-shaped metal plate, 3-5 mm in diameter and 8-9 mm long. Such a tool is used for small work in the household by pressing on its pointed end, giving it rotation around its axis, and using friction, it drills holes in various materials. It can be used for the same purpose to reduce friction in mechanics. Authorship is attributed to engineer V.N. Ter-Gigayzrov.
