摘要

Provided are: a nut that makes it easier to change the position at which the nut is fixed compared to the prior art even when said nut is attached to a paint coating device or a soldering device and deposits that occur when either of these devices is used for a long period of time adhere firmly to said nut; an attachment for a nut; a screw shaft; and a soldering device that uses the nut, the attachment for a nut, and the screw shaft. The nut 10 is screwed onto a screw shaft 2 having a predetermined length. The nut 10 is provided with: a non-engaging section 11 comprising a notched section 12 formed by notching a screw thread parallel to the forward movement direction of said nut 10; and a flange section 13 comprising a connection hole 14 for connection with another member. As a result of this structure, the notched section 12 operates so as to scrape off deposits 6 when the nut 10 is moved forward or backward.
