DMM Brass I.M.P. Nut
Here's what other sites are saying:
IMP's (Immaculate Marginal Protection) are 'brass' micro wires that have a regular taper. They are the ideal basis for any experienced leader's rack of micro gear. The heads are machined on a new 9 axis CNC from a copper alloy that has very specific properties and a carefully controlled hardness; when developing these nuts we gradually honed in on an alloy and a hardness that allowed both good bite and also a good resistance to shear forces - this way the nuts lock into the rock well and also resist being pulled through the placement. The heads are then silver soldered onto stainless steel wire and every unit is proof loaded to 75% of its rated strength. We have developed and built a custom, induction heated silver soldering system that allows us to accurately control the amount of heat applied to each unit during the soldering process - an essential step in ensuring consistency in the final product. 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 sets. #1: 4g/4kN/Blue #2: 8g/5kN/Red #3: 10g/5kN/Grey #4: 13g/7kN/Purple #5: 16g/7kN/Green Note that this item of climbing safety equipment is non-returnable.

DMM's IMP stands for Immaculate Marginal Protection, and these Brass Nuts go in clean and come out strong. Choose from among the 5 sizes and know you're grabbing the appropriate one each time - identify each by the color-coded swage treatment on the stainless wires.
