BLACK DIAMOND Wired Hexentric #7
These useful hexes from Black Diamond are the mainstay of every trad climber's rack. Incredibly versatile, the Hexentrics are perfect for widening cracks where cams are sliding out. Take a close look at one of these and you'll notice they are asymmetrical, with flat sides and a slight taper near the end. This means each of these nuts offers three different widths when turned on their axes, and an additional one when placed end-wise. These Hexes are super easy to rack up, and each one comes with a braided galvanized steel cable. Don't start climbing without some of Black Diamond's Wired Hexentrics in your rack.
