About the DMM Torque Nuts
The Torque Nut shape fits well in normal crack placements, but they have the extra advantage of working extremely well when placed in a camming position.
They come with a doubled-up sling that can be extended when necessary. When racked they will hang neatly off your harness without getting in the way. Just 4 do the work of 6 old-school hexes and because of their offset shapes, they fit into a multitude of crack scenarios.
