For indicating relative rotational displacement between a fixed first member, such as a stud (20) on a wheel hub, and a second member, such as a wheel nut (22), which is rotatably engaged with the first member, a safety device (24) comprises a body (26) having a bore formed with equispaced grooves enabling the device to be releasably secured to the second member (22) in one position of a plurality of positions and having indicating means, such as a pointer (28), to indicate the position of the device (24) relative to a reference, such as a mark (32) on t...
1. A safety device for use with a reference to indicate relative rotational displacement between a first member and a second member which are relatively rotatably engaged with each other, the device comprising:a body having a bore formed with equispaced grooves enabling the device to be releasably secured to the second member in one of a plurality of positions; a cap which fits into or onto one end of the body to close off the bore, the cap being non-rotatably mounted into or onto one end of the body and being removable to allow inspection of or access t...
