shoulder screw hardware in Toolbox not available?

SolidWorks Toolbox has smallest available shoulder screw of 6.5mm.  This is a 5mm x 0.8 thread with an available shoudler length of 16mm.  I can not find this part ANYWHERE in the real world.  The engineer spec'd this part part because it was in Toolbox.  Now I am stuck with completeing the design with a part that is not available for purchase.  That means redesign....not good for productivity.  Does anyone know why this particular size part is in Toolbox if it is not readily available for purchase?  Any comments would be greatly appreciated.
