A set of 4 DMM Micro Wallnuts that are smaller than a Wallnut 1.
These micro-wires are made from a harder alloy than the regular Wallnuts as they must stand up to shearing out of the rock. Combined with a larger surface area (when compared to Brass wires), reduces the chance of the climbing nut being pulled through its placement.
Generally you will find that you will want a variety of micro protection, to give the best chance of getting the right choice of gear in small but often necessary placements. The DMM micro Wallnuts would be one of many suitable choices to fulfil your microwire selection.
*Each Micro Wallnut in this set of four (sizes 0, 00, 0.5, 0.75) is anodised in matt grey, rather than the usual individual colours (yellow, black, blue, red) for each nut.
