Abstract
There is provided in a preferred embodiment of the present invention a maintenance device having a central body and a lubricant container attached to the upper end of the central body. At a lower end of the central body, at least one dynamic body is provided and biased by a spring to an extended position relative to the central body. The dynamic member comprises a pair of cleaning arms that are outwardly biased. As a compression force is applied to the dynamic body, the biasing spring is compressed and the dynamic body is moved toward a retracted position relative to the central body. As the dynamic body retracts, the cleaning arms pivot inward and engage the fastener for cleaning.
