Torque Nuts are DMM's solution to large  passive protection. As the name suggests these nuts have an extremely efficient camming system, as well as working well in standard placements. The four sizes cover a range from thin hands to regular fist, carrying on in size from  large wallnuts. The extendable dyneema slings works  in a similar way to the slings on DMM cams it's protected on the top by a large countersunk groove.
