Method and Tape for Adhesive Locking of a Threaded Fastener

1 . A method for locking a male threaded fastener to a female threaded fastener comprising:

providing a sheet of flexible backing material having disposed thereon a filler material containing adhesive microcapsules to form a thread-locking tape;

wrapping the thread-locking tape around a male threaded fastener; and

installing the male threaded fastener into a female threaded fastener so that the adhesive bursts from the microcapsules and is distributed into contact with the threads on both the first and second fasteners.

2 . The method of claim 1 further comprising the backing material being paper.

3 . The method of claim 1 further comprising the backing material being Teflon tape so that the Teflon tape reduces the friction encountered during the installation of the male threaded fastener.

4 . The method of claim 1 further comprising the tape being wrapped on the male threaded fastener with the filler material facing the threads and the filler material being pressed into the threads and being sufficiently pliable to be retained upon the male threads.

5 . The method of claim 4 further comprising the additional step of peeling the backing material off of the filler material prior to installing the male threaded fastener into the female threaded fastener.

6 . The method of claim 4 further comprising said backing material being shredded by its engagement with the threads of the female threaded fastener during the installation of the male threaded fastener into the female threaded fastener so that the backing material does not prevent the adhesive from contacting the threads of the female threaded fastener.

7 . The method of claim 1 further comprising after disposing the filler material on the backing material, then applying another layer of the backing material so the filler material is sandwiched between two backing materials.

8 . The method of claim 7 comprising removing one of the layers of backing material from the filler material prior to wrapping the tape around the male threaded fastener so that filler material is exposed to the threads and formed into the threads sufficiently to retain the tape on the male threaded fastener without bursting the microcapsules.

9 . The method of claim 8 further comprising after wrapping the tape around the male threaded fastener then removing the other of the layers of the backing material so that upon the installation of the male threaded fastener into the female threaded fastener and the consequent bursting of the microcapsules the adhesive will be exposed directly to the threads of the female threaded fastener.

10 . The method of claim 8 further comprising after wrapping the tape around the male threaded fastener then installing the male threaded fastener into the female threaded fastener and the threads of the female threaded fastener shredding the other layer of backing material so that the adhesive bursting from the microcapsules the adhesive will be exposed directly to the threads of the female threaded fastener.

11 . The method of claim 1 further comprising the adhesive microcapsules all containing the same one part adhesive.

12 . The method of claim 1 further comprising the adhesive microcapsules including first microcapsules containing one part of a two part adhesive and second microcapsules containing the other part of a two part adhesive, and the threading of the male fastener into the female threaded fastener bursting the first and second microcapsules and mixing the one part and the other part.

13 . A method for locking a male threaded fastener to a female threaded fastener comprising:

providing at least one sheet of flexible backing material;

disposing a pliant filler material containing adhesive microcapsules onto the backing material to form a thread-locking tape;

wrapping the thread-locking tape around a male threaded fastener and pressing the pliant filler material into the threads so that the thread-locking tape becomes embedded upon the male threaded fastener; and

installing the male threaded fastener into a female threaded fastener so that pressure is applied and to burst the microcapsules thereby distribute the adhesive into contact with the threads on both the first and second fasteners.

14 . The method of claim 13 further comprising the additional step of peeling the backing material off of the filler material prior to installing the male threaded fastener into the female threaded fastener.

15 . The method of claim 13 further comprising said backing material remaining in place during the threading of the male threaded fastener into the female threaded fastener and being shredded by its engagement with the threads of the female threaded fastener during the installation of the male threaded fastener into the female threaded fastener so that the backing material does not prevent the adhesive from contacting the threads of the female threaded fastener.

16 . A thread-locking tape for adhesively locking a male threaded fastener to a female threaded fastener comprising:

a sheet of flexible backing material;

a filler material disposed on the sheet of flexible backing material;

a micro-encapsulated adhesive disposed within the filler material;

said filler material being sufficiently pliable to enable pressing of the filler material into the threads of male threaded fastener when the thread-locking tape is wrapped around the male threaded fastener so that the filler material is retained upon the threads; and

said micro-encapsulated adhesive being released upon the threading of the male threaded fastener into the female threaded fastener.

17 . The thread-locking tape of claim 16 further comprising said backing material being of a material that is either removable by peeling from the filler material before threading of the male threaded fastener into the female threaded fastener or a material that is shredable by the threads of the threaded female fastener so that the adhesive is released into contact with the threads of both the male threaded fastener and the female threaded fastener.

18 . The thread-locking tape of claim 17 further comprising a second layer of backing material disposed over the layer of filler material so that the filler material is sandwiched between two layers of backing material.

wrapping the tape around a male threaded fastener; and

installing the male threaded fastener into a female threaded fastener so that the adhesive bursts from the microcapsules and is distributed into contact with the threads on both the male threaded fastener and the female threaded fastener.

19 . The method of claim 17 further comprising the backing material being paper.

20 . The method of claim 17 further comprising the backing material being Teflon tape so that the Teflon tape reduces the friction encountered during the installation of the male threaded fastener.
