DMM Brass IMP Set 2-4

The DMM Brass IMP Set 2-4 contains the 3 more used sizes of IMP nuts. I.M.P  stands for Immaculate Marginal Protection which sums it all up pretty  well. They are used when standard nuts are becoming a bit too big and  you want to get a bit of gear in no mater how small. They work  brilliantly in narrow cracks and use an aluminium swage which holds the  wires  parallel but also allows one wire to slide. This means the nut is  loaded more  evenly on both sides. The swage is colour coded too, so  you’ll always  pick the right one from your rack.
