How to Use Hexes

A hexcentric is a hexagonal nut that is attached to a dyneema cord or wire loop and is used when climbers are in need of extra stability. They are mostly just called "hexes." These are important to all types of climbing and even can be used in ice. A hex is placed inside a crack to hold the climber stable through counter pressure. There are many shapes and sizes of the six-sided metal wedge and are available in stores and online. Research and compare the size of cracks that you will encounter before you start investing in too many different sizes, it could become a bit costly. When you are ready to go climbing follow these steps to discover how to use hexes.

Things You'll Need

• Hexcentrics (hexes)
• Nut tool

Instructions

1. Research your climbing area before you begin. Get materials and guides pertaining to the specific area that you will be doing your climbing to see what kinds of hexes to take with you on your climb. There are different sizes to consider and also the weight should be a factor, too.

2. Place the hex into a crack in the rock at an angle. Once you decide where you want to place the chock, check to see what size that you will need. Two of the flat sections of the hexagon-shaped nut should touch the rock on both sides making it a sort of wedge. Make sure to get the flat sides in correctly and evenly.

3. Pull down on the rope to make sure that it is stable and secure. When you create a downward force on the wire, there will be a rotating force created and it will essentially give a camming effect. The rotating force makes an attempt to rotate your metal hex, which will make the hexes lock in place.

4. Use a hammer if necessary. If the crack is only a small amount different than the shape of the hexes that you have, you can use a hammer to gently tap them into place. When you need to place a hex into ice, you can pound a hex into a crack with the hammer, too.

5. Utilize a nut tool when you need to remove the hexes. A nut tool is slim and has a hook on the end to pull out stuck hexes. Due to the sturdy placement and construction of the hexes, it may be necessary to use a tool that is specially designed to retrieve the fused hex nut.
