DMM ALLOY OFFSET NUTS...

Anyway, as I mentioned they come in a set of 5 (smaller offset nuts are available in brass much like the original RP’s), each is rated to 12 kN, they range in size from 12 to 23mm (size 7 to 11), colour coded, are not inexpensive (about $16 ea.) and have a bit of a gap between sizes (I infill this gap with a half dozen of my regular nuts BD nuts) though they can be rotated to make intermediate sizes) but WOW do these things work!  Any kind of flaring or pod like crack as well as many shallow cracks (like the alligator cracking in the Red Rocks varnish that tend to be both shallow and pod like) in the sandstone and these things just slotted in!  They quickly became my go-to for the rest of the trip.  When I got home to Canmore I found that the limestone and quartzite there liked to eat these nuts just as much.  Any placement where the crack edges are a little funky and a regular nut wouldn’t quite seat properly and one of these DMM Offset nuts would just slot in, Bomber: clip and forget.
