The fastening mechanism has a first eccentric member comprising a first collar whose stepped outer diametrical surface closely fits in a complimentary stepped bore in the bracket. The first eccentric member also has a second collar fixed to and eccentric with respect to the first collar. A second eccentric member has a circular portion and a flange affixed concentrically to the circular portion. The circular portion and flange closely fit in the second collar. A socket on the second eccentric member is eccentric relative to the circular member and accepts a fastener, such as a bolt, that attaches a towing lug to the socket.
