Wired Torque Nut 1
Description
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.

The UIAA equipment standard provides a baseline for equipment performance in a test lab under controlled conditions on new equipment. Although these test conditions are relevant to the conditions encountered climbing, conditions encountered at the crags and the condition of the equipment are equally important. This recommendation from the UIAA member federation The British Mountaineering Council (BMC) provides vital equipment information that is NOT explicitly addressed in the standard, particularly failure modes of the equipment and recommendations for the use, inspection, maintenance, and retirement of equipment.
