The DMM Micro Wallnuts are for use in extremely narrow cracks where a normal Wallnut size 1 is too big. The large contact surface area of the Micro Wallnuts allows them to spread loads over a greater area of rock, decreasing the chance of the rock failing. They feature straight sides to give alternative placement options to our other alloy micro-protection. Used in conjunction with Peenuts they provide comprehensive protection for small cracks in friable rock.
