Document Type and Number:
Japanese Patent JP2563069
Kind Code:
B2
Abstract:
PURPOSE: To provide a nail capable of securing a cover to hard material, such as metallic material, and suited for a tool such as an air or electric drill by providing the nail with a stepped shank.
CONSTITUTION: A shank 1 is normally cylindrical and comprises three portions, i.e., a tip portion 4, a penetrating portion 5, and a gripping portion 6. The tip portion 4 is of pointed conical form or may be a diamond type or chisel tip portion which is found to be most suitable. The gripping portion 6 has a substantially constant diameter and a stepped portion 9 slopes away from the penetrating portion 5. The angle B at which the stepped portion 9 slopes is selectable as necessary but an angle of roughly 45 degrees is satisfactory. Neither of the penetrating portion 5 and the gripping portion 6 needs to have a smooth surface. The surface of either of the portions 5, 6 may be roughened and provided with grooves, or otherwise treated as necessary.
