Jesus nut

For example, in 2000, the mast nut of a Bell 206B was removed to be repainted and was not restored and checked prior to a test flight.

Another use for the term is found in rock climbing, in which it refers to the first piece of protection (some of which are also called "nuts") placed on a pitch.

In addition, the Jesus nut prevents the possibility of a factor-two fall onto the belay anchor.

[8] In literature, the term "Jesus nut" was popularized in Chickenhawk by Robert Mason, a narrative about his experiences as a pilot in the Vietnam War.

[citation needed] The award-winning satirical novel The Jesus Nut, by John Prather (published 2021), incorporates multiple meanings of this term as an ironic running joke and deux ex machina.
