Tacking fastener

1. A blind tacking fastener comprising:

a stem comprising:

a gripping portion;

a stem head including a peripheral fraction ring with an outer diameter; and

a body extending from the stem head to the gripping portion; and

a sleeve comprising an inner channel defining an inner diameter, wherein the outer diameter is greater than the inner diameter and wherein the body of the stem passes through the inner channel, and wherein the stem comprises a first material and the sleeve comprises a second material selected such that the fraction ring fractures from the body, in response to a pulling force exerted on the gripping portion, so that: (i) all of the body is removed from the sleeve, and (ii) first and second ends of the sleeve are deformed radially outward to hold and pull together workpieces disposed between the first and second ends.

2. The blind tacking fastener of claim 1 , wherein the fraction ring is operatively embedded within the sleeve as a result of the pulling force.

3. The blind tacking fastener of claim 1 , wherein the sleeve comprises at least one of aluminum or an aluminum alloy.

4. The blind tacking fastener of claim 3 , wherein the stem comprises steel.

5. The blind tacking fastener of claim 1 , wherein the first end has an annular shoulder.

6. The blind tacking fastener of claim 5 , wherein the second end comprises an inner perimeter and an outer perimeter, the inner perimeter generally offset from the outer perimeter.

7. The blind tacking fastener of claim 1 , further comprising a bulb disposed between the fraction ring and end of the sleeve.

8. A method of installing a blind tacking fastener, comprising:

providing a tacking fastener comprising a stem and a sleeve, the stem having a serrated portion and a stem head with a peripheral fraction ring;

inserting the stem and sleeve through one or more apertures of one or more workpieces such that the stem head is on a blind side of the workpiece;

applying a pulling force to the serrated portions sufficient to detach the fraction ring, create deformations at opposing ends of the sleeve to hold and join the one or more workpieces together; and

removing remaining portions of the stem from the sleeve.

9. The method of claim 8 , further comprising selecting a softer material for the sleeve in comparison to a material selected from the stem so to allow for detachment of the fraction ring and removal of the remaining portions of the stem from the sleeve.

10. The method of claim 8 , further embedding the fraction ring within the sleeve.

11. The method of claim 10 , further comprising selecting a softer material for the sleeve in comparison to a material selected from the stem so to allow for detachment of the fraction ring and removal of the remaining portions of the stem from the sleeve.

12. A blind tacking fastener comprising:

a stem comprising:

a gripping portion;

a stem head including a peripheral fraction ring that detaches from the stem when sufficient axial force is exerted on the gripping portion; and

a body extending from the stem head to the gripping portion;

a sleeve comprising an inner channel, wherein the body of the stem passes axially through the inner channel; and

a bulb positioned about the body of the stem, between the fraction ring and the sleeve.

13. The blind tacking fastener of claim 12 , wherein the bulb is a separate construction from the stem.

14. The blind tacking fastener of claim 12 , wherein the bulb is of unitary construction with at least one of the stem head or the body.

15. The blind tacking fastener of claim 12 , wherein the bulb comprises a generally frustoconical cross-sectional shape when not deformed.

16. The blind tacking fastener of claim 12 , wherein an end of the sleeve proximal the bulb is angled towards the inner channel to direct the bulb towards the channel.
