Abstract: Disclosed is a wood screw with a head separated from a threaded extremity by an unthreaded shank whose diameter is less than the outer diameter and only slightly larger than the root diameter of the thread. A cylindrical or tapering neck inserted between the head and the shank has a diameter, at least in the immediate vicinity of the head, equaling the outer thread diameter. The threaded extremity terminates in a pyramidal tip with three or four sides, at least one edge of the pyramid being notched by an extension of the thread groove to act as a spur in cutting a bore ahead of the advancing screw thread. The turns of the thread, in one embodiment, have leading flanks merging into or overhung by rounded ridges enabling the screw to be hammered into a substrate of natural wood or particle-board composition.
