A bolt which extends into the first casing part, into the hole in the barrel nut, and into the second casing part, wherein the bolt engages with the barrel nut so as to join the first casing part to the second casing part; wherein the barrel nut includes a first portion and a second portion, wherein the first portion of the barrel nut is structurally weaker than the second portion of the barrel nut such that, if a predetermined load between the first casing part and the second casing part is exceeded, the first portion of the barrel nut becomes crushed while the second portion of the barrel nut remains engaged with the bolt. The casing assembly may be included in a gas turbine engine.
