ABSTRACT:
A fastening structure is provided to secure a shaft between parallel walls of a box shaped casting which will secure ans locate the shaft without inducing a distortion of the casting walls. One end of the shaft is secured to the adjacent wall and the other end of the shaft is secured through a wall opening using an annular slug and a deformable washer which is compressed by a bolt attached axially to the shaft end to cause the deformed washer to engage the surfaces defining the wall opening. The uniform axisymmetric expansion of the washer does not affect the position of the shaft and the radial fore secures the shaft end without influencing the structure of the casting.
