Abstract: A shroud dampening pin is disclosed including a shaft, a dampening portion at a first end of the shaft, and a cap at a second end of the shaft. The dampening portion includes a bevel having a bevel angle and a contact surface. A turbine shroud assembly is disclosed, including an inner shroud, an outer shroud, the shroud dampening pin, and a biasing apparatus. The outer shroud includes a channel extending from an aperture adjacent to the inner shroud at a channel angle from the aperture. The shroud dampening pin is disposed within the channel. The dampening portion extends through the aperture with the contact surface contacting the inner shroud. The biasing apparatus contacts the cap and provides a biasing force to the inner shroud through the contact surface. The bevel angle is about the same as the channel angle, and the contact surface is about parallel to the aperture.
