When the cracks are too small for DMM Wallnuts it’s time to get out the DMM Micro Wallnuts set. These little beauties work well in narrow cracks because they spread the load through a relatively large surface area. The Micro Wallnuts are machined so that the wire can be recessed onto a full radius inside the nut. This makes them stronger and protects the wire; it also means the nuts will fit into tighter placements. DMM Micro Wallnuts Features: Micro alloy nuts on wire Wire recessed into top of nut and full wire radius for extra strength, durability and reduced profile CNC machined 4 sizes Colour coded for easy recognition Specs: Size Color Strength Weight Range Wallnut 00 Gold 2kN 5g 4.0 / 9.7mm Wallnut 0 Blue 2kN 6g 4.6 / 10.8mm Wallnut 0.5 Red 4kN 9g 5.1 / 11.7mm Wallnut 0.75 Grey 6kN 10g 5.9 / 12.6mm
