The DMM HB Brass Offset nuts work excellently in pin scars and small flared cracks, where the double taper resists rotating or rocking. 

Each face is slightly concave and soft enough to give more "bite" to the placement, and the addition of an aluminium swage, or keeper which holds the wires parallel but allows one wire to slide, means that the nut is loaded more evenly on both sides making the placement more secure. 

Add them to your climbing rack for a boost in strength in the small sizes (compared to other aluminium nuts)
