Manufacturing errors of elements of axial-symmetrical fastenings, as well as assembly errors (incidental assembly) cause that fastenings condition is different that assumed ones by designer. Superposition of such errors is displayed by decreasing of fastening functionality, and in consequence of loss of technological and operating ability. Hence, it is needed to change the approach to axial-symmetrical fastenings designing. One of the main proceeding directions is to take into account the mating of real structure of the shape of transverse and longitudinal section of shaft and hole. In relation to the above it is essential to join achievements of measuring and computing technique for estimation of effort condition of fastening.
