Arranged in a threaded fastener 10 is a pin 15, to which stops 16, 17 are attached at both ends. The distance between the stops 16, 17 is slightly greater than the length of the threaded fastener 10 in the unloaded state, so that the stops can be rotated in relation to the threaded fastener. When the fastener is tensioned, its ends come to bear against the stops 16, 17, so that these can no longer be rotated in relation to the fastener. In this way, it is possible for the tensioning of the threaded fastener to be checked by establishing whether one or both stops can rotate in relation to the threaded fastener. This can also be done when the threaded fastener is not directly visible. <IMAGE>
