RSXSM9 USA 9mm parrots beak/flare nut, no B on tool at all, parrots beak is the same as what crafsman calls "Extreme grip wrench", only difference is the so has a full lip, instead of being milled off as in the craftsman catalog, page 54, 2007-08 c-man power and hand tools catalog! Not listed in my latest so cat., had to make call to dealer to get latest list price. Sorry for the confusion, I need to check my glasses! Thanks for the inquiry, pm if interested. Dan
