rotational movement of the bolt head bevel washer and the nut bevel washer does not occur the central angled spacer sleeve bolt head bevel washer and nut bevel washer are all wedged shape due to the wedged shape of the shims one outer surface is thicker than the opposite outer surface the bolt head and nut bevel washers are rotationally aligned such that their thicker outer surfaces are located at the same azimuth relative to the radial center of the bolt that passes through them the central angled spacer sleeve is rotationally aligned such that it is 180 u00b0 out of rotational alignment with the bolt head and nut bevel washers as shown in fig1 and 2 in a method embodiment of the present invention two wedged central angled spacer sleeves are attached to the first wall segment such that their bolt channels are aligned with the bolt channels of the first wall segment the second wall segment is then placed into contact with the central angled spacer sleeves such that the bolt channels on the second wall segment are aligned with the bolt channels of the central angled spacer sleeves as shown in fig1 and 2 a wedged bolt head bevel washer is then placed on the outside of either the first or second wall segment such that its bolt channel is aligned with the bolt channels of the wall segments a bolt having a bolt head at one end and a threaded end opposite the bolt head is then passed through the bolt channels of.
