Wired Torque Nuts can be used to protect parallel sided cracks. Their shape means they can be used in multiple orientations, giving you a wide range of placement options with every piece. Lightweight aluminium alloy construction means that despite their low weight, each Wired Torque Nut has a 12kN strength rating. Wired Torque Nuts work in all conditions. They are especially useful in winter, when icy cracks cannot be readily protected with cams. The wire that replaces the extendable sling on our traditional Torque Nuts makes them easier to control placing above your head and more resistant to accidental axe strikes in winter.
