A masonry cavity wall tie, comprising:

• a shank having a first shank portion, a second shank portion, and a third shank portion, the shank having a tip at one end and a head at a second distal end, the shank having ductility measured as a bending angle under complete three repeated cycles without rupture of between about 12.5° and 26°;
• the first shank portion commencing at the tip of the shank at a first shank portion first end and extending partially towards the head of the shank and ending at a first shank portion second end;
• the second shank portion commencing at the first shank portion second end at a second shank portion first end and extending towards the head of the shank and ending at a second shank portion second end;
• the third shank portion commencing at the second shank portion second end at a third shank portion first end and extending towards the head of the shank and ending at a third shank portion second end;
• the first shank portion having a helical thread of a first diameter along a predetermined longitudinal length of the first shank portion;
• and
• the second shank portion being unthreaded;
• and
• the third shank portion having a helical thread of a second diameter along a predetermined longitudinal length of the second shank portion,
• wherein the first and second diameters are the same, wherein the second shank portion is between about 25% and about 30% of the wall tie length and wherein the shank diameter is between about 5.5 mm and about 10 mm.
