The square works well in the F-150 spare wheel winch. I tried it for the first time. But I found that the 1/2" drive end didn't have enough clearance as none of my 1/2" drive wrenches or adapters would fit without cleaning the plating and material from the drive end. Otherwise it does what is advertised. I recommend buying the same adapter from Steelman as it has a hex end for the socket.
