When you're high on the wall and the cracks get small, the DMM IMP brass nut set lets you confidently take advantage of the smallest and most marginal placements with 5 sizes of tiny yet mighty IMPs.
Features
Nut heads are made of brass, allowing them to bite into small placements but making them strong enough to resist pulling through
Brass heads are soldered directly on to wires, allowing a thicker wire to be used and increasing the strength of the IMP
One side of the swage is loose and the other is fixed, reducing strain on the wire where it connects to the head
Wire is stiff enough to extend your reach for placement, yet soft and flexible enough not to lift the pice out while you climb past it
