There are lots of nuts on the market, but Wallnuts are amongst the best because of their design, the materials that they are made from and the attention to detail that goes into their manufacture. The end result is that the Wallnuts give secure placements even in difficult situations and their quality means that they will do this time after time, route after route. Pumped and scared the last thing you need is to be fighting in a basic, square nut that won"t seat properly or worse, won"t place at all because the wire is too floppy to allow an accurate placement. Features complex 3D curves and scallops means secure and fast placement in all rock types, DMM"s accurate heat treatment processes on specifically chosen alloys maximizes bite, counter sunk and all the radius"s drilled out to avoid stress points where the wire enters the nut, rumbled well to remove sharp edges that can hinder placement, Either Hot forged or CNC"d from sizes 1 to 6 keeps strength high and weight to a minimum and extruded bar used on sizes 7 to 11 to reduce weight, full size crimp because this is critical to safety, double sealed label upside down for ease, Joint collaboration with Wild Country to standardize color recognition (DMM makes the light weight, colored Rocks for Wild Country).
