Abstract
The present invention provides a screw comprising a head and a threaded shank, wherein the shank is covered with a coating at least 60% of the length thereof from the end, the coating includes microcapsules that contain a viscous fluid with an appropriate level of viscosity. Shavings, including powdered shavings due to friction and exfoliations that may be generated during the screwing process, will be held, so that they will not fall, at the surface of the shank by the viscous fluid coming out of the microcapsules.
