The DMM IMP Brass Nut are part of the 'Immaculate Marginal Protection' range, that allows you to exploit marginal placements. These climbing nuts are the ideal basis for any experienced leader's rack of micro gear.
The nut heads are made from brass which allow for both a good bite and also resistance to shear forces so they can lock into the rock well yet resist being pulled through the placement. The strength is increased due to the heads being soldered directly onto the thicker stainless steel wires.
These wires benefit from a colour coded alloy swage that is only dinked on one side i.e. one wire runs free so that the head is always loaded optimally when it holds a fall. The colour coded swage helps with selecting the right size first time.
These little units come in five sizes and are available either individually or in a variety of money saving sets.
