The threaded portion such as screw, nut or pin comprises a thread, which is partially provided with a coating, which serves to backup the thread after screwing with a counter-thread. The coating contains an UV-paint. Microcapsules are embedded into the UV-paint, where: one part of the microcapsules contains a polymerizable adhesive; and other part of the microcapsules contains a curing agent. An independent claim is included for a method for preparing a threaded portion. |
