Are they like the AWD Sockets/spanners - all wall drive, ie they grip the middle of each nut face rather than the corners?
Those are great! Had a cheap set of them as combi spanners for >20 years, and bought some single sockets shen things were very stuck (use with impact driver, or breaker bar + scaffold pole.
They also work for metric or imperial sizes...handy if you run a mixed fleet!
