ABSTRACT:
A tack member, which is adapted to be joined with a button body for attachment of a button to a garment fabric, has a shank composed of a tapering end portion and a stem portion. The shank has a cold-pressed recess near the tapering end portion. The tapering end portion is in the shape of a pyramid with its tip end disposed off the axis of the shank toward the recess so that the tapering end portion is bendable about the recess as its tip end is forced against the inner side of a cap of the button body during insertion of the shank into a hollow hub of the button body, during which time the stem portion opposes bending or other deformation.
