Nuts are non-adjustable, wedge-shaped (conical) camming devices which provide additional protection in alpine terrain and can absorb longitudinal strain. Unlike camming devices, they passively lock into a narrowing in the rock, while camming devices, on the other hand, actively expand in parallel slits. Nuts can have various basic shapes and are therefore categorized as stoppers, hexentrics or tricams.

Camming devices such as cams and friends can also be used as removable anchors. In the next video, find out how cams differ from nuts and how they are correctly positioned and removed: youtu.be/dTFBPirGWYQ
