After 2 yrs of searching, I finally found FLANK DRIVE wrenches. Gott'em at Harbor Freight in Grand Rapids Michigan.
Flank Drive turns the nut/bolt on the FLATs of the nut/bolt, NOT on the points.
That means that on the open end wrench, the FLANK DRIVE pushes on 4 Flats, instead of 2 points.
On the Box end, the FLANK DRIVE, pushes on 6 Flats, instead of 6 points. Almost Impossible to round off a bolt with a Flank Drive.
Several years ago on this forum, there was an engineer who designed Flank Drive sockets. I think he said that Any Flank Drive will transmit 85% more TQ to the bolt/nut, than any socket. He also said that because of the increased TQ capacity of Flank Drive, the Flank Drive sockets are designed to 185% - 200% capacity of standard impact sockets.
Hey, Flank Drive Engineer, If you get this, PLEASE answer. You have more information that I can remember from what you said!!!
