On the base of experimental results we can conclude that the mini bolt and large internal threads as well as large bolt and mini internal thread combination leads to developing of not satisfied preload. It means that the combination of marginal values of the tolerance field could cause “loose” or “forced” fittings. If we consider the presence of lubricant it could effect the overloading of the bolt connection.
