DMM IMP Brass Nuts

Product detailed description

The DMM IMP Brass Nuts (Immaculate Marginal Protection) are designed to provide security in the smallest and most delicate placements — when nothing else will fit. Perfect for technical trad, alpine, and aid climbing, IMPs allow climbers to protect thin seams, tiny cracks, and shallow constrictions with confidence.

Each IMP features a brass head, chosen for its unique ability to bite into the rock while still resisting deformation or pulling through under load. The nut head is soldered directly to the wire, allowing DMM to use a thicker cable for increased strength and durability compared to traditional micro nuts.

The color-coded swage makes it easy to identify the correct size on your rack and doubles as a self-equalizing mechanism, letting one side of the wire slide slightly to distribute the load evenly during a fall.

Compact, strong, and beautifully machined, DMM IMPs offer the ultimate marginal protection when the rock gives you little to work with. They’re a must-have for climbers pushing into harder grades, where every placement counts.
