PROBLEM TO BE SOLVED: To provide a nail in which a force hitting against a nail head by a hammer is concentrated at an axial center of a barrel part, transmitted to enable an efficient nail hammering work to be carried out.SOLUTION: This invention relates to a nail having a barrel part with an extremity end and a nail head arranged at a side opposite to the extremity end of the barrel part showing a feature that a bottom part having the same with or smaller than a diameter width of the barrel and a protrusion having the same with or smaller surface area than the bottom part and having a height from the surface of the nail head that is the same with or smaller than a distance between an outer peripheral surface of the barrel part and an outer peripheral surface of the nail head and further there is provided a protrusion part having the most protruded high top part from the surface of the nail head.SELECTED DRAWING: Figure 1
【課題】釘頭を金槌で叩打した力が胴部の軸心に集中して伝達されて効率よく釘打ち作業ができる釘を得ること。【解決手段】先尖部を有する胴部と、この胴部の先尖部の反対側に設けられている釘頭とを有する釘において、前記釘頭の表面の中心部の前記胴部の軸心の延長線上に、前記胴部の直径の幅と同等若しくは小さい底部と、この底部と同等か若しくは小さい表面積を有し、かつ釘頭の表面からの高さが胴部の外周面と釘頭の外周面との距離と同等か若しくは低く、更に、釘頭の表面から最も突出した高い頂部を有する突起部を具備したことを特徴とする釘。【選択図】図１
