Publication number: 20180017092Abstract: In an impact-driven threaded nail, a thread has a steep lead angle of about 45° in order to attach a material with the nail by hitting a nail head and causing the threaded nail to rotate. When external force is applied in a direction to pull back the attached material from an underlying material, the threaded nail is often slightly rotated in a loosening direction, thereby generating a gap between the underlying material and the attached material, particularly in the case of the attached material being a thin sheet such as plywood. The present invention addresses the problem of providing an impact-driven threaded nail equipped with a means for preventing the above-mentioned loosening. The solution means resides in that a tapered portion of the head of the impact-driven threaded nail on a back-surface side thereof is formed in a pyramidal shape having a regular polygonal cross-section with a diameter decreasing gradually toward the nail shank.Type: ApplicationFiled: December 17, 2015Publication date: January 18, 2018Inventor: Takeo HASEGAWA
