FAQs
What is the strength rating of the DMM Wallnut Size 1?
The DMM Wallnut Size 1 has a strength rating of 7kN.
What is the weight of the DMM Wallnut Size 1?
The DMM Wallnut Size 1 weighs approximately 15g.
What is the size range for the Wallnut Size 1?
The Size 1 Wallnut is designed for placements ranging from 6.7mm to 14.3mm.
How do the colour codes work?
DMM uses colour-coding to help climbers quickly identify different sizes of Wallnuts, making selection faster on the wall.
Is this suitable for very small cracks?
The Size 1 is one of the smaller sizes in the Wallnut range, suitable for cracks between 6.7mm and 14.3mm. For smaller placements, consider even smaller sizes if available, or micro-protection options.
How does the 3D shape improve grip?
The innovative 3D shape provides more points of contact with the rock surface, allowing it to grip better in irregular placements compared to standard tapered nuts.
What is the corrosion resistance like?
The Wallnut features an anodised finish, which significantly enhances its resistance to corrosion and wear, prolonging its lifespan.
Troubleshooting
Difficulty placing the Wallnut in a crack
Ensure the crack is clean and free of debris. Verify the Wallnut size is appropriate for the crack dimensions (6.7mm-14.3mm). Experiment with different orientations of the nut within the crack.
Wallnut feels loose or insecure
Re-evaluate the placement. Passive protection requires solid rock and constriction. Try a different size or type of protection if a bomber placement cannot be achieved. Ensure the nut is not placed on friable rock.
Anodised finish is scratched or worn
Superficial scratches are normal wear and do not affect the structural integrity of the nut. Continue to inspect for deformation or damage to the wire. If significant damage is present, retire the piece.

Setup, Compatibility & Care
Setup:
- Identify the appropriate crack size for the Wallnut Size 1, which ranges from 6.7mm to 14.3mm.
- Clean the crack of any loose debris.
- Insert the Wallnut into the crack, ensuring it is oriented to maximize contact with the rock.
- Test the placement gently to confirm it is secure and will not easily pull out.
Compatibility:
The DMM Wallnut Size 1 is designed for use with standard climbing ropes and harnesses. It is compatible with most climbing protection systems and carabiners. Ensure carabiners are clipped correctly to the Dyneema sling or directly to the nut's wire if applicable, depending on the specific setup.
Care:
- Cleaning: After each use, clean the nut with a stiff brush to remove dirt and grime. For more stubborn residue, use a damp cloth. Avoid using harsh chemicals.
- Inspection: Regularly inspect the nut for signs of wear, such as deep scratches, deformation, or damage to the wire.
- Storage: Store nuts in a clean, dry place away from direct sunlight and extreme temperatures. A dedicated nut tool or a mesh bag can help keep them organised and prevent tangling.
