DMM Torque Nuts: Best Overall Climbing Hexes

DMM Torque Nuts remain the industry benchmark for active, cam-able protection. These units feature an ingenious eccentric shape that allows them to be placed in an “active” mode, where the nut rotates and cams into the rock under force. This unique design effectively bridges the gap between passive nuts and mechanical cams.

The extendable sling system on these hexes is a standout feature for reducing rope drag on wandering routes. By allowing the nut to be extended without extra quickdraws, climbers save significant weight and simplify their harness clutter. Their size range also covers the awkward gaps where small cams feel insecure and large nuts are too difficult to seat properly.

These are the ideal choice for climbers who want a “do-it-all” piece of passive protection. Whether navigating alpine granite or desert sandstone, the versatility of the Torque Nut makes it a primary rack inclusion. If the goal is a minimalist rack that doesn’t sacrifice security, these are the clear go-to.

Black Diamond Wired Hexentrics: Top Small Pick

When dealing with thin, finicky cracks, the smaller sizes of Black Diamond Wired Hexentrics provide a level of precision that larger hexes simply cannot match. The wire stem allows for a more rigid placement, making it easier to flick the hex into place behind small constrictions. This rigidity is invaluable when reaching high above the head or placing gear in strenuous positions.

The geometry of the Wired Hexentric is designed to offer multiple contact points in parallel-sided or slightly flared cracks. This multi-faceted approach ensures that the piece doesn’t just sit in the crack, but bites into the rock face. It is this biting action that provides the confidence needed to trust gear at the sharp end.

These hexes are best suited for the climber who values a lightweight, snag-free rack for long trad pitches. They excel in tight vertical terrain where every ounce of weight savings impacts endurance. For those looking to replace a set of micro-cams with a more durable, passive alternative, these wired units are the superior choice.

Wild Country Rockcentrics: Best Slung Option

Wild Country Rockcentrics are defined by their sophisticated shape, which is engineered to provide a stable, solid feel when seated in a variety of crack orientations. The use of Dyneema slings ensures that these pieces are incredibly light while maintaining high strength ratings. They are renowned for their ability to nest securely in flares that would cause other protection to walk or shift.

The slung design offers significant advantages regarding movement within the crack. Because the sling is flexible, the nut is less likely to vibrate out of position as the rope moves beneath it. This makes them a reliable choice for longer routes where rope drag and vibration are constant challenges.

Any climber focusing on long, multi-pitch routes will appreciate the reduced weight and increased stability of the Rockcentrics. They are specifically recommended for those who frequently climb on rock types where crack widths fluctuate. If stability in irregular features is the primary concern, these hexes are the definitive selection.

Metolius Curve Hexes: Best Curved Profile

The Metolius Curve Hexes feature a unique, curved geometry that is designed specifically to interface with the irregular surfaces found in natural rock cracks. This curvature allows the hex to maintain more surface contact, effectively spreading the load across a wider area of the rock. This design philosophy reduces the risk of the rock crumbling under high force, which is a common concern on softer rock types.

Beyond the shape, Metolius emphasizes a highly machined finish that keeps the weight low without compromising structural integrity. The curve also helps the hex “self-seat” when tension is applied, creating a secure wedge that resists movement. This makes them exceptionally easy to place quickly during a lead.

These hexes are the best option for climbers who frequent areas with softer or highly textured rock, such as limestone or coarse conglomerate. The curved face provides a level of security that flat-faced hexes often lack in those specific environments. For the climber who prioritizes ease of placement and rock preservation, these are an essential addition to the kit.

Black Diamond Slung Hexentrics: Top Classic

The Slung Hexentric by Black Diamond represents the timeless evolution of traditional climbing hardware. These units use a durable, high-visibility nylon or Dyneema sling that allows for a wide range of motion once placed. They are iconic for a reason; they have been the backbone of trad racks for generations and continue to provide stellar performance in diverse rock conditions.

The strength of this design lies in its simplicity and the sheer volume of experience behind it. Climbers can rely on these pieces to hold in a vast array of crack configurations, from wide chimneys to medium-width cracks. They are incredibly robust, standing up to years of abuse in harsh alpine environments or daily cragging.

If a climber values proven, reliable, and classic equipment, the Slung Hexentrics are the gold standard. They are best suited for those who appreciate gear that performs predictably every single time. Investing in these is an investment in a piece of climbing history that still holds its own against modern designs.

How to Properly Cam and Chock Trad Hexes

Proper placement is the difference between a bombproof anchor and a piece of gear that pops under load. To place a hex, first identify a narrowing in the crack that matches the width of the nut. Insert the hex so that its widest axis is slightly larger than the constriction, then pull down sharply on the sling to “set” the nut into the rock.

For active placements, rotate the hex until the camming side engages with the rock surface. This orientation allows the nut to tighten its grip as tension is applied, mimicking the action of a mechanical cam. Ensure the sling is directed in the direction of the expected pull to prevent the hex from rotating out of its seat during a fall.

Always verify that the rock at the contact points is solid and free of loose flakes or dirt. If the rock is soft, avoid over-torquing the placement to prevent fracturing the edges of the crack. A well-placed hex should feel immobile when tugged firmly in the direction of travel.

Choosing Between Wired and Slung Hex Designs

Wired hexes are generally preferred for smaller, more technical placements where precision is paramount. The rigid stem allows the climber to reach deep into a crack or around an edge without the gear flopping around. They are ideal for quick, efficient placements during hard climbing sequences.

Slung hexes offer superior performance in larger sizes or when the goal is to reduce rope drag over the length of a pitch. The flexible connection allows the gear to move slightly with the rope, preventing the nut from walking or vibrating out of its secure position. They are inherently more versatile for wandering routes where the rope line is not straight.

Consider the intended use when building a rack. A balanced approach involves keeping a few small wired hexes for technical sections, while relying on slung hexes for larger, more substantial placements. This combination ensures adaptability regardless of the terrain encountered during a climb.

When to Rack Hexes Instead of Heavy Large Cams

Large cams are undeniably convenient, but they carry significant weight and size penalties. Hexes are a fraction of the weight, allowing a climber to carry a wider range of sizes without the bulk. For long approaches or alpine routes where weight is the primary enemy, swapping cams for hexes can make the difference between a manageable load and an exhausting one.

Hexes also excel in locations where cams might be problematic, such as heavily flared cracks or frozen, muddy conditions. A cam trigger can freeze or become clogged with debris, rendering it useless, whereas a passive hex remains functional. In remote backcountry areas, the simplicity of a hex translates to higher reliability over time.

Strategic racking is key to a successful climb. Use cams for rapid, repetitive placements on cruiser pitches, but pack hexes for those irregular, awkward cracks that would otherwise require multiple cam sizes. By selecting the right tool for the specific rock feature, a climber can maintain a lean, efficient, and highly effective rack.

Inspecting and Retiring Your Climbing Hardware

Regular inspection of your hexes is a vital safety responsibility. Before every outing, check the nut for cracks, significant gouging, or sharp burrs that could damage the rope. If a hex shows signs of structural failure or deep deformation, it must be retired immediately.

The sling is often the first part of the hex to show wear. Look for signs of fraying, UV damage, or discoloration on the webbing, which indicates that the material is becoming brittle. If the sling is compromised, it can usually be replaced by a professional, but the metal nut itself should also be evaluated for its service life.

Maintaining hardware is not just about safety; it is about extending the utility of your investment. Keep your hexes clean by removing grit and dirt after a trip, especially after climbing on sandstone or wet rock. Consistent care ensures that your equipment remains in top condition for years of climbing, keeping the focus on the ascent rather than gear failure.

Whether you are mastering your first crack climb or refining your alpine rack for a grand tour, these hexes provide the security and reliability needed to push your limits. Keep your gear maintained, choose your placements with intention, and head out to enjoy the granite walls waiting for you. The mountains are calling, and with the right rack, you are ready to answer.
