To provide a nail with a screw capable of increasing a surface area of a multi-threaded screw, to strengthen fixing force obtained by frictional force due to an adhesion portion of a wooden material.SOLUTION: A nail with a screw is composed of a shaft part 4, a head part 2 provided at one end of the shaft part 4 and a sharp part 3 provided at the other end, where a helical multi-threaded screw 5 is formed on the shaft part 4, and a plurality of locking grooves 7 is provided in a mountain part 6 of the multi-threaded screw 5. A long concave groove 10 is formed along a spiral direction on an outer surface of a spiral top part in the mountain part 6 of the multi-threaded screw 5.SELECTED DRAWING: Figure 1
【課題】多条スクリューの表面積を増大し、木質材の密着部分による摩擦力によって得られる固定力の強化を図ることができるスクリューを備えた釘を提供する。【解決手段】軸部４と、この軸部４の一端に設けた頭部２と他端に設けた先鋭部３とからなり、前記軸部４に螺旋状の多条スクリュー５が形成され、この多条スクリュー５の山部６に複数の掛止溝７を設けられたスクリューを備えた釘において、前記多条スクリュー５の山部６で螺旋を描く頂部外面に、螺旋方向に沿って長い凹溝１０を形成したものである。【選択図】図１
