One-piece stud and clip
A one-piece stud and clip is provided by a process working sheet material into a monolithic stud and U-clip fastener. The process includes forming an elongated stud from the sheet material, and bending the sheet material to form the clip. The stud can be a rolled cylinder of the sheet material, or an uninterrupted stud drawn from the sheet material.
1. A process for making a one-piece stud and U-clip fastener from a flat sheet of material including steps of:
shaping the sheet of material to form a flat blank comprising a first distal portion, a second distal portion, and a medial portion;
forming a stud portion pre-form in the flat blank, the stud portion pre-form having a rounded edge;
drawing an elongated stud portion from a section of the stud portion pre-form;
removing the rounded edge from the stud portion pre-form; and
bending the first distal portion or the second distal portion to form a clip portion of the one-piece stud and U-clip fastener, the clip portion having a U-shape integral with the elongated stud portion.
2. The process for making a one-piece stud and U-clip fastener of claim 1 , including threading an outer surface of the elongated stud portion.
3. The process for making a one-piece stud and U-clip fastener of claim 1 , including forming a slot in the stud portion pre-form, and said step of bending performed to position the elongated stud portion in the slot.
4. A process for making a one-piece stud and U-clip fastener from a flat sheet of material including steps of:
shaping the sheet of material to form a flat blank comprising a first distal portion, a second distal portion, and a medial portion;
forming a stud portion pre-form in the flat blank, the stud portion pre-form having a rectangular body that extends distally from the medial portion;
drawing an elongated stud portion from a section of the stud portion pre-form;
forming a slot in the rectangular body; and
bending the stud portion pre-form to form the one-piece stud and U-clip fastener,
wherein the step of bending positions the elongated stud portion in the slot.
5. The process for making a one-piece stud and U-clip fastener of claim 4 , wherein forming the rectangular body of the stud portion pre-form includes removing a rounded portion of the stud portion pre-form.
6. The process for making a one-piece stud and U-clip fastener of claim 4 , including threading an outer surface of the elongated stud portion.
7. The process for making a one-piece stud and U-clip fastener of claim 4 , wherein the elongated stud portion extends through the slot.
