Rock Climbing Nuts

Nuts are metal wedges that we place in the rock's cracks for protection. They provide very good safety and give us the ability to use them in crevices of various sizes(3mm - 20 cm). The nuts are considered to be "clean", ecological, safeties because they can be used many times without being damaged or damage the rock. They come in a very big variety of sizes. The main types of nuts are stoppers, hexes and cams.

Stoppers

Stoppers are the most simple nuts. They have four effective facets and two from which the metal wire goes through. The latest types of stoppers have their facets curved. Most climbers prefer the curved than the flat stoppers. The curved stoppers give more safety because they adjoin a bigger surface of the rock. They fit in crevices from a size of a nail to that of a finger and are sold in numbered series of 10 pieces(No1-No10).

Hexes or hexcentrics

Hexes are bigger nuts and their assymetrical facets are very practical for bigger, angular crevices. The hexes with a piece of rope or kevlar are more handy than the ones with a metal wire. They provide very durable safety points and are possibly the cheaper stoppers. Hexes are manufactured in various sizes and are numbered from No1 to No10.

Camming devices or cams

Cams(spring loaded camming devices-SLCD) are eccentric devices with adjustable size which have 3 or 4 "teeth". They also come in various types and sizes from No1 to No5 with half sizes too. Cams need attention and experience to be placed safely in the rock. They are very useful means of safety but much more expensive than other nuts.
