Nuts

Nuts come in different forms and shapes and sizes, their simplest form being a small piece of metal attached to a loop of wire. They are used by setting them in a small crack in the rock and then tugging on them to set them in. Most nuts are made of aluminum.
The smallest of nuts are known as micronuts, and are commonly made of brass, and have the wire soldered into them, unlike larger nuts, where holes are drilled in them, and the wire is made to pass through it. The most commonly used types of nuts are hexentrics and tapers.

Hexentrics

Hexentrics, commonly called hexes, are used to break a climber’s fall if one should occur. Hexes are basically nuts, which are more of hexagonal prisms, with their threading made of webbing, or a cord. Again, hexes also come in various sizes, ranging from 10mm to 100mm. Some hexes are made with smooth, curved sides, which make it easier to remove from the rock surface.

These pros can be used as either active or passive, and are used by alpine mountaineers as a replacement for SLCDs, because they are lighter, and have lesser moving parts.

Spring Loaded Camming

Devices A spring loaded camming device, also known as ‘SLCD’, ‘cam’ or just ‘friend’, is essentially protection equipment used by rock climbers and mountaineers.
It has three or four cams which are mounted on either one or two adjacent axles. There is a piece of webbing connected to the axle as well.
