DMM Torque Nut Set 1-4

 Torque nuts are DMM's solution to large passive protection.

As the name suggests, these cunningly sized and shaped nuts work well in standard placements but also have and efficient camming system. Just four sizes cover a very large size range. The colour-coded double dyneema sling is protected on the top by a large countersunk groove and works in a similar fashion to the slings on our cams. This unique refinement makes racking the units much easier and allows you to climb less encumbered.

Although Torque Nuts can be used as a wide wedge, their biggest advantage is based on the camming principle of the original hexes. Keeping the all important pivot points but with a modern redesign, we've developed a piece of passive protection kit that is immensely strong yet very light. Rated at 14kN this equates to holding approx a 1.4 tonne static load. Just four sizes cover a very large range and they are all anodised for recognition and corrosion protection.

Those of a certain age may recall the early hexes, a.k.a. seagull bashers, heralding your arrival at the crag as they swung around your legs like cow bells. But they worked and in the days before spring loaded cams they offered the only means of protecting certain cracks.

Skillful placement of Torque Nuts will still work in some places where cams simply aren't as effective. An important consideration is that cams point load the rock while Torque Nuts spread the load - the greater the area of the nut in contact with the rock the wider this load is spread. Bear this in mind if climbing on soft rock for example and to maximise the nut's holding power. Torque Nuts will also be the choice of protection for iced-up cracks over a spring loaded cam.

The Torque Nuts have a double Dyneema sling arrangement (patent pending) that allows you to easily minimise rope drag but without them bashing you in the knees when they are racked. A groove on the top of the nut protects the sling.
