SPARE WHEEL FIXING BOLT WITH HANDLE INSTEAD OF HEXAGON. Origin. To improve design. Experimental Test Report. We have always used a handle on the bolt for fixing Phantom spare wheels, but on the 20 HP. a hexagon is used which needs a spanner. It is now proposed to use a handle similar to the Phantom.
