Brass Offsets are crucial for protecting small flared cracks, often fitting perfectly where nothing else will go. The brass used for the head of the nut is soft enough to bite into placements, but hard enough to resist deforming & pulling through.
Wires are soldered directly into the nut head, allowing a thicker wire to be used & increasing overall strength. The colour coded swage gives easy size selection & allows the Brass Offset to self equalise when loaded, making the most of marginal placements.
