DMM IMP Brass Nuts


IMP’s let you take advantage of the smallest and most marginal placements. Nut heads are made of brass, allowing them to bite into small placements but making them strong enough to resist pulling through. These are soldered directly on to wires, allowing a thicker wire to be used and increasing the strength of the IMP. The swage on the wire is colour coded for quick size selection and allows one side of the wire to slide, letting the IMP self equalize when loaded and increasing placement security. IMP’s are invaluable for those pushing into harder grades and need to take advantage of all protection options.

  • Micro protection for small cracks which lets you protect cracks which normal sized pieces would not fit. Having these wires on your rack gives you more options.
  • Wires soldered directly into heads for strength. This allows a thicker wire to be used, increasing the strength rating of each nut.
  • Brass heads for optimal characteristics in marginal placements.
  • Passive protection works in wet and icy conditions. Unlike active protection such as cams, passive protection can be used in wet or icy cracks, where friction is reduced.
