Abstract
A shear bolt can include a body having a shear portion. A port in the body may be used for introducing a fluid into the body. A core disposed in the body may include a chamber at least partially surrounded by the shear portion. A fluid pressure in the chamber and exerted against the shear portion may be increasable in response to the fluid being introduced through the port, such as to increase an amount of stress in the shear portion and prime the shear bolt for shearing. Additionally or alternatively, a support structure positioned in the chamber may be frangible to reduce support to the shear portion in response to the fluid being introduced through the port, for example, to contribute to priming the shear bolt for shearing.
