A plug (1) for masking a threaded hole on spray painting, powder painting and similar processes includes a threaded portion (3) for screwing into the hole. The threaded portion (3) is manufactured from an electrically conductive material. A head (2) of a non-conductive material is disposed at the one end of the threaded portion (3) for screening-off the hole and its threads. The head (2) is advantageously provided with a recess (5) for cooperation with a suspension device. The inside of the recess (5) is electrically conductive and is in communication with the threaded portion (3). |
