Loading... Please wait...DMM is bringing an old favourite back to the market. The high demand for these nuts is because their complex offset shape offers placement opportunities when nothing else will fit.
These nuts are based on the famed HB Alloy Offsets and were produced using modified versions of the original HB dies. In typical DMM fashion we have brought them into the 21st century with colour coded sizing, recessed wires and lightening holes in the largest two sizes.
Features
DMM's accurate heat treatment process optimises the physical property of the alloy to maximise bite.
We've recessed the top of the nut and countersunk all other drilled radiuses in order to avoid stress points where the wire enters the nut. This also totally protects the wire from abrasion damage.
The nuts are all rumbled well to remove sharp edges that can hinder placement
The wire used on each nut is chosen so that the nut can be placed at full reach without them flopping around.
We use a full size crimp because this is critical to safety
The label is upside down so you can check the size easily when they are on your harness. The label is double sealed so that it does not tear with time and use.

If you are looking to supplement your wires than these come highly recommended.
First of all the set covers the sizes most often used which is nice if you want to double up on those. Size 7 to 11 is about equivalent with DMM or WC wires size 4 to 8 and the colour coding matches with WC Rocks and DMM Walnuts.
When taking these out first it takes a while to spot placements but after a while a whole new world of formerly hard to protect rock turns suddenly into the most solid pro. The Shape of the Offset nuts makes it possible to get good placements in uneven shaped cracks, where a normal wire would make hardly any contact. It is surprising how many cracks seem to be made especially for these wires.
A other nice touch is that the swage is only fixed on one side, meaning it is easy to even the wire strands and ensuring that the wire gets weight evenly in a fall. On one of the first version people mentioned that the heads tend to slip down, this doesn’t seem to be the case with the current ones.
