Something that serves something that has Kedushah, such as a Sefer Torah is considered Tashmishei Kedushah. However, something that serves something that has no Kedushah, even if the thing it serves is used for a Mitzvah, has no Kedushah. The Kelim (like the Shulchan and the Menorah) may be considered Tashmishei Mitzvah, as they serve something which is for a Mitzvah. If we say that they are considered Tashmishei Kedushah, because the things they serve have Kedushah in that they are Kodshim then we could in fact say that since they themselves also have Kedushah, even those things that serve them, such as the coverings used in the desert, are considered Tashmishei Kedushah. However, it is questionable whether the fact that they are Hekdesh or Kodshim is enough for them to be considered like a Sefer Torah. Perhaps only a Sefer Torah that has Kedushah in its own right is considered Kadosh as far as this Din applies.
