If they look familiar it’s because they have the same tapered faces and side profile as DMM’s tried and tested Wallnuts. The reduced width makes them ideal for shallow cracks, pin scars, and situations where every gram counts. The combined weight of the 1-11 Halfnut sets are 42% lighter than the equivalent Wallnuts and they are similarly colour coded. Shape provides additional protection options and the reduced width aids stability in shallow placements. Colour matched shrink tube for easy identification.
