Abstract: A full-round head nail having an offset head is configured with a gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the round head such that no heel is formed at a point tangential to both the head and the shank. The gusset has a lofted surface tapering radially from a roundness at the zero heel to a taper at the toe. The gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied.

Abstract: Described is a press-in element for pressing into a non-pierced or pre-pierced component. The press-in element has a head part having a ring surface confronting the component and a neck part which projects away from the ring surface, i.e. from the component contact side. The head part further has a ring-like projection surrounding the neck part with a radial spacing and projecting away from the ring surface. The neck part has a radially outwardly projecting ring bead, which can be formed as a continuous ring bead or as a ring bead interrupted at points. The apex of the ring bead has an axial spacing from the ring surface which is larger than the axial spacing of the apex of the ring-like projection from the ring surface, which lies radially within this projection and together with it and the ring bead forms a pocket which receives material of the component.

Abstract: A method to make a flanged pin is described. The method includes feeding wire through a forming die whereby the wire is deformed to create a straight pin. The straight pin is then fed from the forming die to a heading die having a pre-formed cavity where a first portion of the straight pin is located in the forming die and a second portion of the straight pin is located in the heading die. A portion of the pin is secured in the forming and heading die, having a portion of the straight pin disposed in a gap defined by a space between the heading die and the forming die. As the die gap is closed, the portion of the straight pin is displaced into a pre-formed cavity thereby creating a flange.

The intermediate portion includes a first substantially constant diameter section that extends from the first end toward the second end, a first tapered section that extends from the first substantially constant diameter section, a second substantially constant diameter section that extends from the first tapered section, and a second tapered section that extends from the second substantially constant diameter portion to the second end. The pin fastener further includes a knurled section formed in the second substantially constant diameter portion.

At least one, and preferably both, lateral edges of the metal ribbon are knurled or serrated so as to assist in anchoring the ribbon to the sleeve.

Abstract: A nail having an offset head is configured with a multi-step support gusset formed integrally between an undersurface of the offset head and a superior portion of a shank. The head of the nail is relatively thin, and the shank is positioned radially off center of the head. A first portion of the gusset defines an angle relative to the shank axis and the second portion of the gusset defines an angle relative to the shank axis different from that of the first portion. The support gusset reinforces the junction of the shank with the head, supports the toe of the head, and distributes the force of a load on the head through a longitudinal axis of the shank, preventing the toe from bending or yielding and prevents the shank from yielding to the stresses of the load applied.

Abstract: The present invention relates to a tool for the manufacture of an offset head nail, said nail comprising a shank and a head, said head being placed with its center being offset to the center of the shank, wherein said tool is one of a set of at least two tools acting mutually on a blank for a nail, said tool comprising a front side with a reception opening and a top side to be used when forming the head, said reception opening being shaped to form an impression in the blank and to fixate said blank during forming of a head on the blank. The invention further relates to a use of the aforementioned tool. Nails with offset heads are used in nail guns, where a strip of nails is used for shooting multiple times before reloading a new strip of nails.

Abstract: A method for manufacturing a nail efficiently at low cost without a loss of material. The nail includes two legs bound together by a washer. One of the legs has a protrusion such that when the other leg is driven, it will spread by riding on the protrusion. In this method, a round rod stock is pressed except a portion thereof to form a head at one thereof, a trunk portion having a semicircular section with a flat surface between the head and the portion, and a tip portion at the other end of the rod stock. The portion forms the protrusion. The one of the legs is thus formed. The protrusion may be formed by pressing the rod from both sides.
