A torque limiting fastener comprises a body. The body defines a first body portion and a second body portion that extend from a first end of the body to a second end of the body. The body comprises an inner surface extending from the first end of the body to the second end of the body. The body further comprises an outer surface extending from the first end of the body to the second end of the body. The body yet further comprises an inner threadform extending substantially along a length of the inner surface of the second body portion and a controlled break region. The controlled break region is disposed at an intersection of the first body portion and the second body portion. The controlled break region includes an outer surface break point formed into the outer surface and an inner surface break point formed into the inner surface.
