Embodiments of the present invention will be described below in detail with reference to the drawings.

In the present invention, a metal fitting 1 is provided with a head 2 and a shank 3 integrally, and a conventional nail, screw, bolt or the like is used as it is, except for the points described later. Can be. In the illustrated embodiment, a so-called screw nail in which the top surface of the head 2 is formed flat, the shank 3 is provided with a sharp end 4 at the tip thereof, and a coarse screw 5 is formed on the outer periphery of the shank 3 is shown. The nail which can be driven by a nailing machine is illustrated. However, the fastener according to the present invention has a screwdriver formed on the head 2 with a screw-engaging portion such as a plus or minus groove, and has a shank 3 and a screw which can be screwed by a power screwing machine. Etc., and may be other fasteners.

As shown in FIG. 1, a large number of fasteners 1 are arranged in parallel, and the heads 2 and 2 of the adjacent fasteners 1 and 1 and the vicinity of the tip of the shank 2 are mutually connected. In a state where the heads 2 and 2 are almost joined to each other, a mutual joining point 6 of the heads 2 and 2 and a mutual joining point 7 near the tip of the shank 2 are adhered with adhesives 8 and 9, respectively. The unit body 10 is constituted by a set of fixed metal fittings. The adhesives 8 and 9 are made of, for example, a metal-adhesive resin-based adhesive.
Each of 9 constitutes connection parts 8a and 9a which can separate the fastener 1 from the unit body 10 one by one.

In the unit body 10, the parallel fasteners 1 are substantially joined and bonded between the heads 2, 2 and the vicinity of the tip of the shank 2, so that the number of fasteners 1 arranged in parallel is increased. As the unit goes, it is formed in the shape of a donut-shaped disk as shown in FIG. 1, but when the unit body 10 is used for a power-driven screwing machine or a driving machine (power tool), the number of the fasteners 1 is further increased. By increasing the width, a helical disk may be formed as shown in FIG.

In the present invention, the unit body 1 of the fastener 1
0 is not necessarily used exclusively for a magazine-type power tool, and may be used manually by using a hammer or the like one by one in the same manner as the normal fastener 1 such as a nail. That is, the fastener 1 is separated from the unit body 10

As described above, the side-by-side fasteners 1 and 1 are bonded to each other by the adhesives 8 and 9, so that the joints 6 and 7 are bonded in a state where they are in contact with each other. In some cases, they are bonded in a non-contact state with an adhesive interposed. Therefore, it should be understood that the term “substantially joined state” described in the present invention includes both such a contact state and a non-contact state.

By the way, as shown in the figure, in the present invention, the places where the bonding is performed by the adhesives 8 and 9 are preferably both the joining place 6 of the head 2 and the joining place 7 near the tip of the shank 3. However, the unit body 1 targeted by the present invention
As long as the shape retention of 0 is possible, the location to be adhered by the adhesive 8 or 9 may be at least one of the junction 6 and the junction 7. However, in the case where the unit body 10 is formed by bonding only one side, it is desirable to perform bonding at the joint 7 near the tip of the shank 3.
