Title:
NAIL
Document Type and Number:
Japanese Patent JP2620476
Kind Code:
B2
Abstract:
PURPOSE: To provide a nail which can produce a strong drawing resistance even in the case of a material having weak holdability, such as gypsum board, etc.
CONSTITUTION: One end 3a of a bar portion 3 bent like a U-shape is fixed to a flange portion 2, and another end 3c of the bar portion 3 is inserted movably into a through hole 2a of the flange portion 2 so as to project by definite length. Because the end 3c is driven through the flange portion 2 in such a state that the flange portion 2 abutts a body and the drive of the end 3a of the bar portion 3 has been stopped, the tip end of the bar portion 3 expands in the lateral direction. Thus, it is possible to produce a strong draw resistance.
