The DMM Alloy Offset Set fills the gap on a trad rack that a standard stopper set leaves open: the features where parallel walls don't exist. The offset taper lets one face engage a narrow surface while the other seats against a wider one, which is exactly the geometry of a flared crack or a pin scar that a symmetrical nut can't grip. Sizes #7 through #11 address the mid-to-larger crack band where flared and irregular features are most common. What Our Gearhead(R) Experts Are Saying:"Offset nuts are the piece I reach for when a standard nut skates right past a placement: pin scars, flared constrictions, shallow pockets where a symmetrical nut just won't bite. The stiff wires make full-reach placements manageable without the nut flopping around, and the recessed wire attachment is the longevity detail worth noticing when comparing worn cables on a standard piece."
